Frozen Shrimp: To Use or Not to Use?

20090828shrimp.jpg

[Michele Humes]

The best seafood is nearly always the freshest seafood. And the best shrimp are the freshest shrimp—right?

Jessica at Food Mayhem disagrees, citing five reasons that frozen shrimp are actually better. Her argument? Frozen shrimp are:

  • Of a higher quality—since nearly all American shrimp are frozen and then defrosted, frozen shrimp haven't yet gone through their final thaw
  • Much cheaper
  • Able to last far longer
  • Available to purchase in bulk
  • Clearly labeled with their origin, size, and weight

What do you think? Are you partial to fresh or frozen shrimp?

I have no issues at all using frozen shrimp. I typically have a bag in the freezer.

I don't even understand why this is a question.

Unless you live on the ocean, then any "fresh" shrimp you get at a fish counter is previously frozen.

Absolutely the best shrimp are the freshest shrimp. And when you live inland, then the freshest shrimp are often the ones that are still frozen - instead of hte ones that have been frozen, shipped, thawed, and then sold.

Why is this even in question?

I live in the midwest, so there's no such thing as "fresh" shrimp. Frozen works for me.

I almost always use frozen shrimp. I've personally never noticed a major different in quality between the frozen and fresh stuff but maybe I'm not very picky about my shrimp! It's easy to defrost and then I can keep it on hand as a last-minute addition to any meal :)

Also, if you live inland and buy "fresh" shrimp which has been frozen and then thawed, you have no idea of knowing how long ago that thawing took place. I find that shrimp much older than a day or so lose their sweetness and are therefore pretty blah.

Does anyone know how long frozen shrimp is kept frozen before being sold? Is shrimp that's sold as "fresh" frozen for a shorter period of time than shrimp sold while still frozen?

Yeah... all shrimp is frozen. On the boats that catch them, I think, so even if you live on the beach, unless you net them yourself, you're eating frozen. I think maybe the question is about whether they're cooked and frozen...

And there, I'm not so sure. Freezing anything twice is bound to be bad for taste and texture.

Yeah, this question kinda doesn't make sense, since all shrimp are frozen on the boats. You're basically paying more not to have to thaw them. And the question of how long they've been unthawed in the store is a good one - buying frozen shrimp just makes more sense.

Being a Floridian I can get fresh shrimp but there's always the chance they are lying to you and selling you frozen shrimp from China that has been thawed. I'd rather go to a retailer I trust and pay for good domestic frozen shrimp than take my chances.

Same for buying any expensive fish like grouper, there's a good chance you are getting cheated so stick with a retailer you can trust and buy what they offer.

I don't eat shrimp anyway, never did like them all that much and fishing for them is incredibly destructive to the marine environment, possibly the most destructive form of fishing.

Non-frozen shrimp are defrosted shrimp.

Three rules for purchasing frozen shrimp:

1.) Must be WILD (not farm raised)

2.) Must be IQF (individually quick frozen)

3.) No smaller than 16-20 (aka "jumbo")

I always keep a bag of wild, IQF 16-20s in the freezer. Perfect for quick, easy weeknight stir fry dinner, to stretch leftover takeout Chinese, quick shrimp cocktail, etc...

Frozen works just fine for me. I control when to thaw.

I live on the coast, but still use frozen shrimp all the time! Their benefits really out weigh the fresh from. They thaw quickly and still maintain a good texture and quality. Normally, I would go for fresh when purchasing seafood, but frozen shrimp still seem to cut it for me!

Fresh is always better. We get fresh spot and sidestripe in the season. By fresh I mean NEVER FROZEN. Let me tell you they are delicious. Most of the time when you buy them whole with the head still on, the females will be clutching a big fat red clump of eggs in the legs. Great stuff for a shrimp pasta sauce.

That being said, when the fresh ones aren't in season frozen is good too. I always try to buy whole shrimp as I think they are better preserved. No flesh exposed to water/ice that degrades the flesh.

My problem with those bags of frozen shrimp is that the shrimp are usually treated with something. The one time I bought them, they were too salty to eat. I would swear that I saw on America's Test Kitchen that you can get untreated frozen shrimp but I've never seen them in any market I've shopped in.

Ninety percent of the shrimp served in the U.S. and in other countries comes from the tropics. It is harvested in non-sustainable ways. I live in Costa Rica and endangered sea turtles regularly wash up on shore with their fins cut off, dead from drowning, from getting caught in shrimp nets. For every pound of shrimp harvested, an average of ten pounds of other baby fish and aquatic wildlife are killed and thrown overboard. Some of the shrimp here are farmed. The farms are generally constructed where mangrove swamps, another very important and fragile ecosystem, have been cut down for this purpose and ponds are made to raise the shrimp. After the shrimp are harvested, the water in the ponds is released into the mangroves. Unfortunately the nitrate level is so high that many of the already fragile mangrove fish and other aquatic animals are affected.

If you are in the US, please check the country of origin for shrimp, fresh or frozen, prior to buying it and choose responsibly. Here is a good website with info about responsible seafood selection - http://www.edf.org/page.cfm?tagID=1521

With any frozen product, such as shrimp, two issues are paramount: how they are frozen, and how they are thawed. You don't really have much control over the first, but for reasons I will not go into, "flash" freezing is superior and the sooner after caught the better. But you do control the thawing. Common advice is to place the shrimp (or other product) under a stream of cold water. Don't do it, except in a pinch----because it degrades quality. The ideal way to thaw is slowly under refrigeration---like overnight, or pulled out of the freezer in the morning, if you are using that night. This slow thaw allows for a minimum loss of internal moisture-- the biggest threat from thawing. Have you ever thawed something at room temperature and found the product in a pool of water? Did you ever wonder where that water came from? Well, basically, if came from inside the product due to cellular breakdown in the freeze/thaw process,and you need to do everthing you can to minimize this effect. You can't eliminate it, but you can certainly reduce it. "Flash" freeze, slow thaw.

"fresh" shrimp aren't that much better than frozen (I guess because as many comments above pointed out, they are previously frozen) unless they are still alive prior to cooking.
sorry. I'm a cruel Japanese.
I'd happily use frozen shrimp and not expect them to taste like live shrimp.

I follow the same rules as Truff, and almost always have a bag in the freezer. Even living on the coast with ready access to a good amount of fresh seafood, it's difficult to find never-been-frozen shrimp.

Just had some tonight, pan seared and served with pasta and pesto with fresh-from-the-CSA-share basil.

The real question is between frozen cooked shrimp (don't use) and frozen raw shrimp (totally fine). I have always found the cooked shrimp to be awful.

I live in California, so I have access to a lot of fresh stuff. Frozen shrimp is something I just can't do. It HAS to be fresh. I'll admit it... I'm spoiled.

We have access to live shrimp in Hawaii, so for me fresh is the way to go whenever possible.

The costco frozen are amazing in quality.

I think the Costco shrimp are really good too.

I too am spoiled. We have a fishmonger in our market, who sells fresh, never-frozen prawns when he can get them, and only when he can get them. I'm sure our local Chinese restaurant uses frozen, and for their prices I would have no right to complain.

My father-in-law runs a shipping company, and is paid quite well (under the table) to drive as fast as possible to carry crates of prawns, langoustines and oysters on ice from the shore to a certain restaurant at about 6 a.m.

Interesting bit of trivia: there was a fish market in London which, prior to licence reform, had a pub with a 'reverse licence'. It opened at 11 at night and closed at 11 in the morning.

My wife is allergic to shellfish so I really haven't investigated this thoroughly. Can you get frozen 'head-on' shrimp?

@Joerob7 you are absolutely correct, thawing is where frozen will be worse for wear than fresh. I live in Shanghai. which gets me both fresh and frozen shrimps. The problem with frozen shrimps is that if you thaw them out improperly (too fast) the shrimp will lose its elasticity and bite, instead becoming powdery or dusty in texture. Anyone else know what I mean?

@kellycakes: where on the coast do you live? I do as well.

See, this is an interesting question. I have no problem with keeping convenience foods [like frozen shrimp]. There are simply some things that are helpful and okay to accept as, well,...just 'good'. Right?
BUT I'm thinking of all the insanely beautiful shrimp I've had on the Gulf Coast here..straight from the harbor, straight from the coolest markets, etc. There is really and truly nothing like a properly treated bunch of shrimp. I crave them like crazy in the summer.
So, my contention and point would be that:
a) the IQFs are fine to keep around for quick and casual meals
b) the stops must be pulled if it is to be a decent/proper seafood-centric meal. Only the best in this case.

Ooh, this is a good chance to pass on my favourite tip regarding prawns (and shellfish in general). Sautee them in butter and garlic (gently) and add a few split vanilla beans...they nicely complement the saltiness of the fish and the taste of the garlic. Alternatively, you can marinate them in garlic, olive oil and vanilla before grilling.

Frozen wild shrimp have some kind preservative/chemical on them that foams up when you run water over them. Whatever it was, it made me sick and I avoid frozen shrimp at all cost. Oh, and the taste was inferior to fresh. No contest for me, always get fresh and my guests will usually comment on the good flavor.

I only have access to frozen shrimp, and I seldom buy cooked ones. However, Aldi's cooked shrimp isn't half bad and it's quite inexpensive. I don't much like trying to cook with it, but I'm trying to watch what I eat and it sure does make a healthy snack dipped in a little cocktail sauce.

I live in North Carolina and fresh shrimp are available in season. And when I am sure of the source, they are the way to go. However, year-round I keep individually frozen jumbo shrimp from Trader Joe in the freezer for the convenience and they taste just fine -

As an aside to those who buy frozen tilapia, please check the packaging. I just dumped 8 fillets because I didn't check before purchase - they came from China and the ingredients were listed as: Tilapia and CARBON MONOXIDE.

Hope the moderators forgive me for straying off topic here, but can one buy pine nuts in the US that don't come from China? I know I can't avoid food with Chinese ingredients, but at least I can avoid things that are clearly labeled.

Actually, topics surrounding food origins, safety and/or sustainability might be an interesting idea for their own thread.

ChloeA, if you google "pine nuts from USA" you will find a number of sources. I recently bought pine nuts grown in the USA and it was either at Trader Joe or Whole Foods.

The real question is:

Cooked frozen or Raw?

I always go frozen raw.

As a native New Orleanian, I am totally spoiled by seafood of all sorts and have impossibly high shrimp standards. Fresh-from-the-ocean Royal Reds are my favorite (they taste like Maine lobster!), but fresh gulf shrimp are phenomenal, too. I've had them alongside frozen shrimp and there was a HUGE difference in plumpness, sweetness, size, and color. Fresh shrimp all the way, beyond a shadow of a doubt.

My family fished commercially growing up, and I also lived on a farm where shrimp were raised. Eating fresh shrimp most of my life has ruined me. I think freezing seafood leaves it flavorless. To make it worse, restaurants and prepared food makers are always trying to mask the fact that the shrimp are flavorless after so much time from water to plate. They put too much garlic, breading, and other strong flavors that interfere with the shrimps great texture and flavor.

I never buy frozen shrimp and rarely eat it in restaurants unless I know the place gets it from the sea.

My preference is for fresh -- I have fond memories of eating pounds and pounds of freshly caught, boiled shrimp with my mother, accompanied with little dishes of soy sauce and chopped Thai chiles.

In comparison, I've only been able to find frozen shrimp in the Philadelphia suburbs, and it's enough of a difference that I find myself not eating as much as I used to.

I like to use them in my Asian Soups; probably the only time tho

is this an issue of frozen RAW or COOKED shrimp?

As just about everyone else has already remarked:
1) There is no such thing as "fresh" shrimp unless one gets them right at the dock, since essentially all shrimp you can buy at the markets are pre-frozen or were once frozen.
2) I always keep a bag in my freezer. I often make a soup, then throw a handful straight into the broth with some Thai chiles, ginger, a squirt of Siracha and whatever else is on hand. Tom Yum-ish, I guess.

I live on frozen raw shrimp. I make enchiladas and stir fries and pasta dishes and shrimp salads...everything. It's just so much cheaper, and I really don't see the difference. The only time I insist on buying the freshest I can find is when they stand alone: like grilled jumbo prawns. Then, and perhaps I only imagine it, I think I can tell the difference. But I don't feel the same way about frozen scallops, or lobster tails, or fillets of fish. It really does change the texture. But, shrimp, I don't know. They seem to work.

Luckily, I live within 10 miles of the Pacific Ocean, so fresh shrimp aren't quite an extravagance. I will say that uncooked, peeled, tail-on shrimp rock since they tend to be a whole lot cheaper than the fresh variety and much easier to work with. They work remarkably well as a mix-in for paella and stir frys, but I'd never use 'em for ceviche.

Frozen raw (shell-on) : definitely use. I usually have a bag in my freezer.

Frozen cooked: avoid at all cost (no flavor, mealy texture)

I am of the opinion that location of harvest is more important to me than fresh or frozen. Atlantic coast shrimp taste better than foreign or gulf shrimp can't say about Pacific shrimp. I buy during the shrimp season only and when I find really tasty shrimp, I freeze them. They still taste fine upon defrosting.

I totally agree. If you thaw slowly and cook them properly, frozen shrimp are delicious. There also soooo cost effective: buy at a warehouse store and use only what you need. No waste=money saved! I feel the same about the frozen scallops I get at the warehouse store.

these types of posts are offensive.

they are nonsense. they offer no basis in actual industrial process. they offer no quality analysis.

get your heads out of your asses and do something marginally close to journalism.

otherwise, quit the bullshit business.

@dbisping: Our intent, in this post, was to draw attention to a writeup elsewhere on the Internet and ask for the opinions of our Serious Eats community on the topic—that is, whether frozen shrimp have their merits.

At Serious Eats, we aim to foster discussion about a wide variety of topics, some of which we on staff or as writers spend time exploring ourselves, some of which, like this, are simply intended as conversation starters. We believe that there's a great deal of collective knowledge in our online community and want to tap into it whenever possible. Posts like this allow us to do so.

@Carey Jones: so get in the business of informing people.

these types of posts don't foster conversation, they foster confusion. lots of the posts on this site do that. it's both frustrating and off putting to be part of an audience that's being treating that way.

there wasn't any analysis. there wasn't any background info. there was only regurgitation and that was pretty limited.

there isn't any controversy to teach here. even the concept is ridiculous, but that's the lazy and insulting presentation i keep seeing here.

raise the bar and quit dumbing down your content.

@dbisping, you are looking for Cook's Illustrated Online. This isn't that.

I grew up cleaning fresh shrimp on the Atlantic Coast, and as a result I hated shrimp. The someone told me about cooked, frozen shrimp. I thaw them in cold running water and I never by any chance cook them or add them directly to hot preparations--but, for numerous salads, cocktails, sushi and garnish preps, they are awesome.

I agree that they taste flavored. Much better than I could.

dbisping, if this site is so distasteful to you, why don't you just drop out - you sound pretty offensive in your defensiveness - I'm sure you could find the information you so badly need, starting with good manners, by googling. I am almost 90 years of age and am always amazed by disgruntled people like you who feel superior for no valid reason.

Personally, I have no problem with frozen shrimp. However, my question has to do with what is being sold as "fresh". I live in Miami, FL. I recently went to Homestead, FL to a "farmer's market". While there I realized much of the product sold was from California, not locally grown produce. So I wonder if the non-local mentality has carried over to other categories.

To my question. There is a fish monger selling head on green shrimp at the same farmer's market. However it says it comes from the Gulf. Is it possible to buy Gulf shrimp that has never been frozen on the Atlantic side of the state? I guess I should ask the question this way...Does anyone have experience buying head on green shrimp that you know for certain has not been frozen?
Maybe the better question is...how can I tell if head on green shrimp has been recently caught? these shrimp are displayed as Alton Brown recommends with piles of ice in a free draining container.

Any guidance would be greatly appreciated.

HI everyone, fun to read all these comments on this topic I wrote since I didn't get nearly as many comments on my site (although some people clearly did not read what Carey or I wrote).

Wondering if anyone has any recommendations on sources for frozen scallops since I haven't found one I liked yet. I had written them off after a few bad experiences but several people here seem to have had good experiences.

I have never seen fresh shrimp in our area so I have to buy frozen. I like knowing i have them in the freezer ready to go for a quick meal. I am 5 minutes away from making shrimp cocktail, shrimp scampi, or chinese shrimp stir-fry. If I had access to fresh shrimp, I would love it. But I don't. I am sure the flavor is probably better but there is nothing I can do about this except move somewhere south - such as FL, LA or GA.

Here's a tip for the lovers of fresh shrimp who can only get them in season. We used to go to the shore in NC and get them right off the boat and in those days they were fresh, heads-on. We would buy 100 lbs--back then they were $2.00/lb--and then eat our fill. With the rest, we would use a "paper" milk carton, fill it with sea water, and freeze them. If you thawed out a carton--placed it in the fridge over night--you could eat the shrimp in cocktail or any way you wanted, and they tasted the same as they did fresh. Now, this was in the '60s, so I don't know about the pollution factor of sea water these days, and don't live in NC anymore. However, in SoFL we do get fresh Key West pink shrimp every now and then and they are great. On the west coast, if I get over there, I try to get fresh gulf shrimp--big ones! They are truly excellent as shrimp cocktail.

Cheers!

I'll only use frozen shrimp or scallops for that matter if added to a stew... otherwise you need the fresh stuff to grill/sear.... oh yea - I have made the mistake.

I have no problems with frozen shrimp that are wild caught from the USA. I won't go near farm raised and/or imported shrimp. The link below is an article written by Jim Carrier for Orion Magazine. If you love shrimp it is important that you take the time to read this article. Thanks to Mark Bittman for bringing it to my attention. Now, read and learn:
http://thirdcoastcuisine.blogspot.com/2009/09/shrimp-truth.html

karacooks - is right on! If you want freshest possible shrimp it's got to be frozen JUST THAW IT RIGHT! Upon harvesting shrimp and it hits the deck it sterts to deteriorate, as in rot, so it has to be iced or frozen stat! The question should have been saltwater shrimp versus fresh water and the origin. I feel the Mexican Guaymas Whites are the best available and they are frozen. The Guaymas whites are the sweetest and claenest tasting of all. In the mid '79's the Japanese signed a 30 year contract with the Mexican Government Co-operativo to purchase the entire catch of these shrimp so they weren't available anywhere but from Japan. A few years ago the contract expired and the Mexican Gov't saw the error by locking in a price and wouldn't renew the contract so now they are available here in the U.S. Try the Catalina Seafood Company in San Diego put in a little effort and get the best.

A little fun fact: Sushi grade fish is always previously frozen to kill any potential harmful parasites. There really is no such thing as fresh seafood when you buy it in stores. And many of us have never tasted fresh shrimp since we don't catch and cook it ourselves on the same day.
