Why It Works
- A balanced sauce has plenty of vinegary kick to balance out the cloying sweetness of most restaurant versions.
- Cooking the aromatics for the sauce at a lower temperature lets their flavors develop without having to superheat your wok or skillet.
- Vodka's higher volatility and ability to inhibit gluten formation leaves you with a superior crisp crust when added to the chicken coating.
- Adding some of the marinade to the dry coating mixture creates little nuggets that cling to the chicken pieces, adding more surface area for extra crunch.
If the British can proudly call chicken tikka masala their national dish, then surely it's time that General Tso got his chicken in our national spotlight. After all, ask yourself this question that Jennifer 8. Lee, journalist and author of The Fortune Cookie Chronicles asked in a TED talk: how many times a year do you eat Chinese food versus the supposedly all-American apple pie?
According to Lee, there are 40,000 Chinese restaurants in the country—more than all of the McDonald's, Burger Kings, Wendy's, and Kentucky Fried Chickens combined. And whether it's called General Tso's (as it is here in New York), General Gau's (the way I knew it through my college years in New England), Cho's, Chau's, Joe's, Ching's, or, as they call it in the Navy, Admiral Tso's, walk into any one of those restaurants and chances are you'll find it on the menu.
Its origins are still up for debate. Its namesake, General Zuo Zongtang, almost certainly never tasted the dish before his death in 1885 and, as Lee discovers, his descendants—many of whom still reside in the General's hometown of Xiangyin—don't recognize the dish as a family heirloom, or even as particularly Chinese, for that matter.
As my friend Francis Lam reported in this fantastic piece on the origins of General Tso's chicken, Ed Schoenfeld, proprietor of New York's Red Farm and one of the world's experts on Chinese-American cuisine, traces its origins to Chef Peng Jia, a Hunanese chef who fled to Taiwan after the 1949 revolution. Made with un-battered large chunks of dark meat chicken tossed in a tart sauce, it was more savory than sweet. It wasn't until a New York-based chef, T.T. Wang, learned the recipe from Peng in Taiwan, brought it back, added a crispy deep-fried coating and sugar to the sauce, and changed the name to General Ching's that it stuck, eventually making its way onto Chinese menus across the country and the globe. It's so popular that there's an entire feature length film on its origins.
It makes sense: As Lee says, we Americans like our food sweet, we like it fried, and man, do we love chicken.
The details may vary—you'll see everything from broccoli to canned water chestnuts to mushrooms to (eek!) baby corn added to versions around the country—but the basics are the same: You start with chicken with the kind of crisp, craggy, deep-fried coating that Colonel Sanders himself would be proud of (what is it with military men and fried chicken anyway?), then toss it in a sweet and punchy sauce flavored with garlic, ginger, scallions, and dried chiles. Throw it all on a plate with some steamed white rice and you've got one of America's most popular dishes.
It also happens to be one of the safer options on Chinese-American menus. Even the $5-with-a-can-of-Coke-and-egg-drop-soup lunch special at the sleaziest college take-out joint hits your taste buds in that sort of hangover-craving kind of way that a McDonald's Chicken McNugget dipped in Sweet 'N Sour Sauce manages to nail time after time. And yet, I firmly believe that it has the potential to be so much more than that. How great would a homemade version of General Tso's be, with a flavor that shows some real complexity and a texture that takes that crisp-crust-juicy-center balance to the extreme?
I'm smart enough to know that one should never get involved in a land war in Asia. Luckily, this was a battle I could fight in my own kitchen at home. I rolled up my sleeves and headed into the fray.
Knowing that getting the crisp coating on the chicken right was going to be the toughest challenge, I decided to get the sauce out of the way first.
Though Chinese restaurants often brand General Tso's with a token chile or two next to its number on the menu, its flavors are really more sweet and savory with a bracing hit of acidity than actually spicy. Shaoxing wine (a Chinese rice wine similar in flavor to dry sherry), soy sauce, rice vinegar, chicken stock, and sugar are the base ingredients, and they all get thickened up into a shiny glaze with a bit of cornstarch.
I looked at several existing recipes and tasted versions of the sauce from restaurants all around New York. Most restaurant versions are syrupy sweet, while home recipes range from being cloying to containing almost no sugar at all. I found that plenty of sugar is actually a good thing in these sauces, but that the sugar has to be paired with enough acidity to balance it out. I settled on a mixture of 2 tablespoons wine, 3 tablespoons dark soy sauce, 2 tablespoons vinegar, 3 tablespoons chicken stock, and a full 1/4 cup of granulated sugar, along with a teaspoon of toasted sesame oil and a tablespoon of cornstarch to thicken it up.
Even with the basic liquid ingredients balanced, the sauce tasted flat and boring without aromatics; in this case, they're ginger, garlic, scallions, and some dried whole red chiles.
Here's one of the great things about making General Tso's at home: you don't need a wok.* See, General Tso's is not really a stir-fried dish. It's deep fried chicken tossed with a sauce. The only place that stir-frying might come into play is with cooking those aromatics.
*I mean, you don't need need a wok for any Chinese dish, but if smoky, deep wok hei is your goal, it certainly helps.
I tried cooking a couple batches of sauce side by side. One I made the traditional way: oil heated until smoking hot, with the aromatics added in and stir-fried for just 30 seconds or so before adding in the liquid ingredients and letting the sauce simmer and thicken. The second I made by starting the same aromatics in a cold pan with oil, heating them while stirring until aromatic, then adding the liquids.
I fully expected the high-heat version to have superior flavor, but when tasted side by side, we actually preferred the easier, lower-heat version—the garlic, ginger, and scallion flavor was more developed and blended in more smoothly with the other ingredients.
As for the chiles, if you have a good Chinese market, they should be easy to find, though red pepper flakes will do in a pinch.
Another great thing about General Tso's is that you can make the sauce well in advance—heck, you can even make it the day before if you'd like—and just warm it up to toss with the chicken when it's good and ready for it.
A First Attempt at Chicken Coating
To start my chicken testing, I scanned through various books and online resources, pulling out recipes that claimed to solve some of the problems I was looking at—namely, a crazy crunchy fried coating that doesn't soften up when the chicken gets tossed with sauce. Though similar, there were variations across the board in terms of how thick the marinade should be (some contained only soy sauce and wine, others contained eggs, and still others were a thick batter), whether or not to toss with dry starch or flour after marinating, and whether to use light or dark meat chicken.
I put together a few working recipes that seemed to run the gamut of what's out there to test, including:
- Thin marinade of soy sauce and wine, tossed in cornstarch before frying.
- Egg white-based marinade, tossed in cornstarch before frying.
- Whole egg-based marinade, tossed in cornstarch before frying.
- Egg-based batter made with cornstarch, no dry coating before frying.
- Egg-based batter made with cornstarch, with a dry coating before frying.
- Egg-based batter made with flour and cornstarch, no dry coating before frying.
- Egg-based batter made with flour and cornstarch, with a dry coating before frying.
Here are a few of the results:
They all look alright, but none of them stayed crisp for long, even before they were added to the sauce. From testing, one thing was certain: a thicker, egg-based marinade is superior to a thin marinade, which produced chicken that was powdery and a crust that turned soft within seconds of coming out of the fryer.
Adding a bit of starch to the marinade before tossing it in a dry coat was even better. Better, but not perfect. The General may have won this battle, but he will lose the war, I swear it.
The other takeaway? Dark meat is the way to go. Breast meat comes out dry and chalky, a problem that can be mitigated with some extended marinating (the soy sauce in the marinade acts as a brine, helping it to retain moisture), but the process adds time to an already lengthy recipe, and even brined white meat is nowhere near as juicy as dark meat.
And who are we kidding? General Tso's is never going to be health food. Break out the thighs for this one (and check out our guide to deboning 'em).
General Tso's Chicken Requires a New Coating Approach
None of the existing techniques I found gave me quite the coating I was looking for, so I decided to start expanding my search, pulling out all of the chicken-frying tricks in the book.
What about double-dipping? I started my chicken pieces in a thick marinade made of egg white, soy sauce, wine, baking powder and cornstarch (I found that adding baking powder to the batter helped keep it lighter as it fried), then dipped it into a mixture of cornstarch, flour, and baking powder (adding flour helps with browning).
After that I moved it back to the wet mixture, and again into the dry, creating an extra thick coating.
Extra thick coatings produce extra crunchy chicken for sure. Too crunchy, unfortunately. Getting close to a quarter inch thick in parts, the coating made the General Tso's taste more like tough crackers than anything. Extra leavening didn't help.
Next I went for a different approach, looking to Korea for some clues. I had already spent a good deal of time perfecting a recipe for Korean fried chicken, and that recipe tackles a similar problem: how to get battered, deep fried chicken wings to stay crisp when coated in sauce.
The solution there? Use a thin slurry of cornstarch that's been cut with vodka, an idea that I first saw in British chef Heston Blumenthal's Perfection series. The vodka can help fried foods get crisp in two important ways.
First, alcohol is more volatile than water (and soy sauce, wine, and eggs are basically water). That is to say, it evaporates more readily, and since frying is essentially a process of evaporation, batters made with alcohol tend to come out crisper.
Vodka also serves to limit gluten development. Why is this important? One of the issues I was finding with my fried chicken chunks was that the coating, which started out crisp, soon turned leathery as it began to get cool or moist. This is a result of overdevelopment of gluten, the interconnected network of proteins that forms when flour and water are mixed. You want some gluten in the mix (without it, you end up with a powdery, papery crust), but too much can be an issue. Because gluten does not form in alcohol, vodka lets you achieve a batter that doesn't get leathery as it cools.
I tried coating chicken thigh pieces with the exact same batter that I used for that Korean fried chicken before tossing it in sauce and tasting it.
It was an improvement on the stay-crisp-when-wet front for sure, but it wasn't exactly what I was looking for in General Tso's. It needed more craggy nooks and crannies to capture that sauce.
With the idea of nooks and crannies in my head, my thoughts immediately jumped to my homemade Chick-Fil-A sandwich. The trick there turned out to be adding a bit of the wet batter to the dry mix before dredging the chicken in it. By working that wet batter into the dry mix with your fingertips, you create little nuggets of breading that stick to the exterior of the chicken.
After deep frying, those little nuggets help increase the surface area of the chicken, making it extra crunchy and crisp.
In retrospect, thinking of fast food seemed like such an obvious move. After all, those Chicken McNuggets stay crisp for hours, and if you've been following along for a while, you'll know of this little hack: use Popeye's chicken nuggets in Chinese-American stir-fries instead of frying your own chicken. It just makes sense to start this dish with really great chicken nuggets, right?
By combining that method with the vodka trick I learned from my Korean fried chicken, I ended up with even better end results. The best of both worlds:
And the best part? Those sauce-catching crags stay crisp for a long time—so crisp that even microwaved the next day, the chicken is almost as good as it was freshly-fried.
Tips for Pulling It All Together
For flavorful and crisp chicken, start with a marinade of an egg white mixed with a couple of tablespoons of dark soy sauce, a couple of tablespoons of Shaoxing wine, and a couple of tablespoons of vodka. Set aside half of this mixture to moisten up my dry coating later on, then finish the coating with cornstarch, baking soda, and the chicken.
At this stage, you can refrigerate the chicken for up to a few hours, or you can plow straight through the rest of the recipe with a shortened marinating period. It makes very little difference.
Add that reserved marinade to the dry mix of flour, cornstarch, baking powder, and salt. The mixture should look coarse and crumbly, with a few big nuggets of the flour-marinade mixture.
You can just dump all the chicken in and then work on carefully separating and coating each piece in the mixture, pressing firmly so that it adheres (you will get messy hands using this method), or you can use my preferred method, which takes a bit more practice: Holding the dry mix in one hand and tossing constantly, drop individual pieces of chicken in one by one with your other hand. As you toss, the chicken pieces should all get individually coated.
You may have heard me say it before, and I'll keep repeating it until evidence to the contrary arises: unless you have a deep fryer, a wok is the best vessel for deep frying. Its wide shape makes it easy to maneuver food and helps catch spatters, keeping your countertop clean as you cook.
All of the normal caveats about deep frying hold true here: use a thermometer to regulate temperature (350°F (177°C) in this case), add pieces one at a time and gently lower them into the hot oil (don't drop them!), and keep things moving so that they fry rapidly and evenly, which in turn will help them get crisper faster.
Once the chicken is fried and drained, it's just a matter of tossing it with the pre-made sauce. (I like to add a few 1-inch pieces of scallions to the mix, but that's totally optional.) A rubber spatula does the trick. It takes a bit of work to get the sauce to coat every surface, but you will be rewarded when all's said and done.
It was a long, twisted road to get here, but with a mix of chicken-frying techniques and a sauce that balances its sweetness with just the right amount of acidity, I believe I finally have a version of this most American of Chinese dishes that even the General's family would approve of.
For the Marinade:
1 egg white
2 tablespoons (30ml) dark soy sauce
2 tablespoons (30ml) Shaoxing wine (see note)
2 tablespoons (30ml) 80-proof vodka
3 tablespoons (24g) cornstarch
1/4 teaspoon (1g) baking soda
1 pound (455g) boneless, skinless chicken thighs, cut into 1/2- to 3/4-inch chunks
For the Dry Coating
1/2 cup (64g) all-purpose flour
1/2 cup (64g) cornstarch
1/2 teaspoon (2g) baking powder
1/2 teaspoon (1.5g) kosher salt
For the Sauce:
4 tablespoons (50g) granulated sugar
3 tablespoons (45ml) homemade or store-bought low-sodium chicken stock
3 tablespoons (45ml) dark soy sauce
2 tablespoons (30ml) Shaoxing wine (see note)
2 tablespoons (30ml) Chinese rice vinegar or distilled white vinegar
1 tablespoon (8g) cornstarch
2 teaspoons (10ml) peanut, vegetable, or canola oil
2 teaspoons (6g) minced garlic (about 2 medium cloves)
2 teaspoons (4g) minced fresh ginger (about one 1-inch piece)
2 teaspoons (4g) minced scallion bottoms (about 1 scallion), plus 6 to 8 scallions, white parts only, cut into 1-inch lengths
1 teaspoon (5ml) toasted sesame oil
8 small dried red Chinese or Arbol chiles (see note)
1 1/2 quarts (1.4 liters) peanut, vegetable, or canola oil for deep frying
Steamed white rice for serving
For the Marinade: Beat egg whites in a large bowl until broken down and lightly foamy. Add soy sauce, wine, and vodka and whisk to combine. Set aside half of marinade in a small bowl. Add cornstarch and baking soda to the large bowl and whisk to combine. Add chicken to large bowl and turn with fingers to coat thoroughly. Cover with plastic wrap and set aside.
For the Dry Coat: Combine flour, cornstarch, baking powder, and salt in a large bowl. Whisk until homogeneous. Add reserved marinade and whisk until mixture has coarse, mealy clumps. Set aside.
For the Sauce: Combine sugar, chicken stock, soy sauce, wine, vinegar, cornstarch, and sesame oil in a small bowl and stir with a fork until cornstarch is dissolved and no lumps remain. Set aside.
Combine oil, garlic, ginger, minced scallions, and red chiles in a large skillet and place over medium heat. Cook, stirring, until vegetables are aromatic and soft, but not browned, about 3 minutes. Stir sauce mixture and add to skillet, making sure to scrape out any sugar or starch that has sunk to the bottom of bowl. Cook, stirring, until sauce boils and thickens, about 1 minute. Add scallion segments. Transfer sauce to a bowl to stop cooking, but don't wipe out skillet.
To Finish: Heat 1 1/2 quarts peanut, vegetable, or canola oil in a large wok or Dutch oven to 350°F (177°C) and adjust flame to maintain temperature.
Working one piece at a time, transfer chicken from marinade to dry coat mixture, tossing in between each addition to coat chicken. When all chicken is added to dry coat, toss with hands, pressing dry mixture onto chicken so it adheres, and making sure that every piece is coated thoroughly.
Lift chicken one piece at a time, shake off excess coating, and carefully lower into hot oil (do not drop it). Once all chicken is added, cook, agitating with long chopsticks or a metal spider, and adjusting flame to maintain a temperature of 325 to 375°F (163 to 191°C), until chicken is cooked through and very crispy, about 4 minutes. Transfer chicken to a paper towel-lined bowl to drain.
Add chicken to empty skillet and return sauce to skillet. Toss chicken, folding it with a rubber spatula until all pieces are thoroughly coated. Serve immediately with white rice.
Shaoxing wine can be found in most Asian markets. If unavailable, dry sherry can be used in its place. If you can't find boneless skinless chicken thighs, you can debone them yourself using this guide. If you can't find whole dried chiles, substitute with 1/4 teaspoon crushed red pepper flakes.
