Why This Recipe Works

  • Trimming and grinding quality meat at home decreases the risk of contamination.
  • Using a store-bought curing packet that's specially formulated for nem chua ensures proper food safety standards along with appropriate seasonings and flavorings.

Whether served rolled into small logs, cut into squares, or bundled in tropical leaves, nem chua—a beloved type of Vietnamese cured pork—manages to deliver on almost every flavor we crave: sourness from lactic acid; a subtle sweetness imparted by banana leaves or sugar; a pungent bite from raw garlic; ample saltiness; floral spiciness from black pepper and funkiness from white pepper; and a good dose of raw-chile heat. “Usually people use plastic or banana leaves, but my grandpa would wrap them in guava leaves,” says Chef Helen Nguyen of Saigon Social, a homestyle Vietnam restaurant in NYC. “It takes on a slightly herbal bitterness and almost smoky taste.”

The geographic footprint of nem chua isn't limited to Vietnam—it edges into Cambodia, Thailand, and Laos, too. In the latter two countries, the name of the finished product is typically written as naem (or sometimes nam) and the preparation also incorporates cooked sticky rice in the mixture. In each area, differences in heat levels, days of fermentation, and methods of forming the preparation make for a nuanced range of possibilities in the final nem chua. However, across all regions, nem chua can be enjoyed both as-is (it's a “perfect accompaniment to an ice cold beer,” says Nguyen), as well as an ingredient in cooked dishes, like naem khao (a crispy rice salad made by frying and crumbling rice balls then mixing them with naem) and phat naem sai khai (naem stir-fried with egg).

From Outdoor Fermentation to Commercial Curing

Although Nguyen considers nem chua a “top 10 dish of Vietnam,” she says that “more education is needed about it [in the US], because people are worried about raw meat.” Hence, she compares nem chua to charcuterie for those unfamiliar with it: “It’s just cured meat, like a cured sausage, or a dry salami.” While the traditional procedure of making nem chua is to let the ground meat mixture ferment naturally outdoors for a few days, the “modernized” process involves a store-bought curing packet that shrinks the timeline to just 24 hours and dramatically reduces variability across batches.

One of the most popular brands, Lobo (which Nguyen also recommends), markets the curing mix specifically as “nam powder.” The information on many packets is typically written only in Thai script, but Hong and Kim from The Ravenous Couple, a Vietnamese cooking blog, sent me one where all the contents were labeled in English. With an ingredient list in hand, I set out to confirm exactly what kind of transformation the raw meat mixture was undergoing.

First, Anna Bauer, a food scientist who works for a major national packaged foods company, pointed out that nem chua made with this packet is a cured, but not fermented, product. “The meat is only in the fridge for 24 hours, and since the packet doesn’t list any microbes in the ingredients, it doesn’t have time to be ‘fermented’.” However, it still takes on a distinct tanginess due to the main ingredient, glucono delta-lactone (GDL), which breaks down “into gluconic acid due to the high level of moisture in raw meat and lowers the pH, hindering the ability for harmful bacteria to grow.” Additionally, Bauer says that because GDL “denatures some of the proteins, it changes the texture of the nem chua.”

The next two main ingredients, glucose and dextrose, are two names for the same molecule and add sweetness to the final product. While this recipe's quick method of nem chua doesn’t leave time for bacterial fermentation, during longer curing methods these types of sweeteners “provide an easy fermentation substrate for microorganisms to munch on,” says Bauer. “Lactic acid bacteria love glucose and will produce lactic acid as it metabolizes the glucose. This further decreases the pH of the sausage and leads to complex flavor development.”

The nicely bouncy, supple bite of nem chua is also partially due to sodium tripolyphosphate (STPP), an alkaline salt that “helps modify muscle fibers to...bind them during the curing process,” explains Claire Thrift, a food scientist who has worked on packaged foods for a range of major businesses, such as Post. “STPP has also been shown to increase migration of salt and nitrites into muscle fiber, ensuring even distribution and thus a safe and effective cure.” According to Bauer, the phosphates are also specifically binding to the water in the meat, which “helps the emulsification by not allowing syneresis [the oozing out of liquid].” The result contains more moisture and is easier to chew, Bauer says—similar to “a Slim Jim versus a jerky.”

For those concerned about nitrite, which is also listed in the ingredients (in sodium nitrite form), Thrift says that the sodium erythorbate present helps “inhibit nitrosamine formation, which are the carcinogenic compounds that form when nitrites and proteins interact in your gut, and are responsible for the bad reputation of cured and processed meats.”

Why use nitrites at all? Because they are necessary to prevent the growth of clostridium botulinum, the bacteria that causes botulism, and offers the “cured” flavor we are now accustomed to. It also changes the final color of the product to a more appealing red.

Safety and Sourcing Quality Meat

While the process of making nem chua with the packet seasoning is very controlled, all the food scientists I interviewed encouraged those who make the dish to be mindful of food safety, cleanliness, and the use of quality meats. Professor Eric Decker, head of the Department of Food Science at the University of Massachusetts, Amherst, says there is potential for trichinosis* when using pork for nem chua, given that the meat is not fully cooked, but this is preventable if the “pork is chemically tested for trichinosis, or frozen at certain temperature and time regimes to kill the trichinosis.” Alternatively, beef may be a better option, although that still constitutes “a microbial risk, just like [eating] beef tartare.”

*Per the CDC: Trichinosis, or trichinellosis, is a type of roundworm infection that results from eating raw or undercooked meat infected with the trichinella parasite, particularly wild game meat or pork. Cases of trichinosis in the U.S. have declined sharply over time (see historical graphs), and now the risk of trichinosis from eating commercially raised and properly prepared pork is very low.

Nguyen, who has trained under Pat LaFrieda and is a meat expert herself, recommends striking up a relationship with your local butcher to source the best meat possible, and using the leanest cut of pork (or, optionally, beef) available when making nem chua (she explains fattier cuts tend to go rancid more quickly). For pork, a tenderloin or loin is a great choice; for beef, beef eye round. Even with those naturally lean cuts, Nguyen will still trim off as much excess fat as possible. She recommends using a meat grinder at home—a “double grind is the best”—but tossing everything into a food processor also yields suitably delicious results.

Adding Pork Skin for a Classic Texture

If you live near a grocery store stocked with Southeast Asian products, make sure to also grab a few bags of cooked, sliced pork skin (typically kept in the frozen section). These thin, translucent strands create the distinct chew in Nguyen’s nem chua, and are generally found in nem chua preparations across Vietnam (including mass-produced varieties). Bite into a piece and you’ll see those little flecks peeking out against the pink flush of freshly ground pork loin, surrounded by specks of garlic, chile, and peppercorn. “It’s not the same without the skin,” Nguyen says, “it’s like eating a cheeseburger without cheese.”

To Nguyen, nem chua is not only a staple of her upbringing—she likens opening the refrigerator and seeing nem to “finding a ham and cheese or bologna”—but also a fond memory of her father, who passed away 10 years ago. “It was one of his absolute favorites,” she recounts. “He would have a beer with dinner and we would eat nem. It’s a snack, it’s bar food, it’s street food, it’s everything!”

Nem Chua (Vietnamese Cured Pork With Garlic and Chiles) Recipe

Prep 60 mins
Active 60 mins
Chilling Time 25 hrs
Total 26 hrs
Serves 16 squares

This Vietnamese raw cured sausage is tangy, salty, and loaded with the funky, spicy, and fragrant flavors of garlic, chiles, and both black and white peppercorns.


  • 2 pounds (900g) boneless pork loin or tenderloin (see note)

  • 1 teaspoon whole black peppercorns (see note)

  • 1 teaspoon whole white peppercorns

  • One 4-ounce (110g) package cooked pork skin, rinsed, drained, roughly chopped (see note)

  • 7 medium cloves minced fresh garlic (25g), plus thinly sliced garlic cloves for garnish

  • 4 red bird's eye chiles (5g), stemmed and minced, plus thinly sliced chile rounds for garnish

  • 2 tablespoons sugar (30g)

  • 1 teaspoon (4g) Diamond crystal kosher salt (for table salt, use half as much by volume or use the same weight)

  • 1 packet (70g) nam powder (including smaller packet of salts inside the main packet), such as Lobo


  1. Line a baking sheet with parchment paper. Using a sharp knife, trim pork loin of as much fat as possible; measure out 1.3 pounds (590g) trimmed meat and reserve any extra for another use (such as a stir fry or ground pork). Cut trimmed pork into roughly 2-inch chunks and arrange on a single layer on the prepared baking sheet. Freeze until very firm but not frozen solid, 15-20 minutes.

  2. If Using a Meat Grinder: Place meat grinder parts in freezer to chill for 1-2 hours before processing. Using the second-smallest grinding die, grind pork into a clean work bowl. Switch to the finest die and grind pork once more into a medium-large mixing bowl.

  3. If Using a Food Processor: Working in batches to avoid filling the processor more than halfway per batch, pulse processor until pork is finely ground, about 2 minutes. Transfer pork to a medium-large mixing bowl.

  4. Using a spice grinder, grind black and white peppercorns to a fine powder. Add ground peppercorns to pork, along with prepared pork skin, minced garlic, minced chiles, sugar, and salt. Using a clean gloved hand or clean spatula, mix well.

  5. Add curing packet (be sure to also add the contents of the smaller packet inside the main packet). Using a gloved hand, thoroughly mix all ingredients together by grabbing handfuls of the mixture, squishing it in your palm, and repeating until the entire mixture has taken on a sticky, paste-like consistency, about 5 minutes.

  6. To Make Square-Shaped Nem Chua: Line an 8-inch square baking dish with plastic wrap. Add nem chua mixture to pan, and, using a spatula, smooth into an even layer. Set 1 slice of raw garlic and 1 chopped round of bird's eye chile into the surface approximately every 2 inches (you want these garnishes to top each square when you cut the nem chua). Cover nem chua with plastic wrap, pressing it firmly against the surface, and refrigerate at least 24 hours and up to 1 week before cutting and eating.

  7. For Sausage-Shaped Nem Chua: Set a 12- by 12-inch square of plastic wrap on a work surface. Spoon 2 ounces (55g) nem chua mixture onto center of plastic wrap. Fold plastic wrap over nem chua mixture, then use your hands to form into a smooth log about 6 inches long and 1 1/4 inches thick.

  8. Peel back plastic and add alternating slices of raw garlic and chiles along the entire length of the log. Carefully fold the plastic wrap back over the nem chua log, then roll once more to form an even cylinder shape. Make sure to squeeze gently as you do this, to remove as much air from the mixture as possible. Twist the ends of the plastic wrap in opposite directions to form a tightly wound cylinder of even thickness.

  9. Repeat with remaining nem chua mixture, then refrigerate nem chua logs for at least 24 hours and up to 1 week before slicing into oblong rounds and eating.

Special Equipment

Food processor or meat grinder; spice grinder; 8-inch square baking dish (optional; for square nem chua only)


You ultimately need 1.3 pounds (590g) trimmed lean pork for this recipe. Getting this final weight is essential because the pork is mixed with a packaged curing product scaled to that weight. Since the quality of the meat and freshness of the grind is very important for food-safety reasons, we strongly advise buying larger pieces of pork and trimming and grinding them yourself. Different cuts, though, will require different amounts of fat to be trimmed away: pork loin, for instance, often has a fat cap that will need to be removed, whereas tenderloin is usually more lean. Two pounds of meat is a safe starting point to guarantee a final yield of 1.3 pounds, but you may end up with extra depending on the specific cut you buy.

If a milder peppercorn flavor is desired, soak peppercorns in water for 15 minutes, then drain and dry thoroughly before grinding.

Based on our recipe testing, packages of Vietnamese prepared pork skin can sometimes be difficult to find, and we have not located an online source yet. If you can't find it, you can leave it out and proceed with the recipe as written. Alternatively, you can make your own by purchasing 4 ounces (110g) raw pork skin (sometimes sold as rind) from a local butcher; boil until the skin can easily be pierced by a knife, about 45 minutes, then drain and transfer to refrigerator to chill. Once cold, slice rind into hair-like strands using a sharp knife, then roughly chop into shorter lengths. It is now ready to be used in the recipe.

Make-Ahead and Storage

Cured nem chua can be kept refrigerated for up to 1 week.
