A copycat recipe of “Tori Kurozu-An” from Ootoya, this Japanese-style Sweet and Sour Chicken uses black rice vinegar in the sauce to create a deep, malty savory flavor.

Sweet and sour dishes from Chinese restaurants are really popular and my children love them whether it’s made with chicken or pork. This Sweet and Sour Chicken however is a little bit different from the typical one you’ve tried. Why?

This savory and delicious fried chicken and vegetables with sweet black vinegar sauce is a copycat recipe of “Tori Kurozu-An” from Ootoya 大戸屋 restaurant.

Japanese Sweet and Sour Chicken

First of all, this sweet and sour chicken is a Japanese style. Did you notice there are several kinds of vegetables in the sweet and sour chicken? This is a copycat recipe from a popular Japanese diner – Ootoya (大戸屋) which specializes in Japanese home-cooking dishes (Katei Ryori 家庭料理). Some of you may be familiar with this restaurant as there are many Ootoya restaurants both in Japan and outside of Japan, including Singapore, China, Taiwan, Thailand, Hong Kong, Indonesia, and also two locations in NYC.

In Japan, we refer to the sweet and sour sauce as Amazu-An (甘酢あん), literary meaning sweet vinegar gravy. On Ootoya’s menu, this recipe is called Tori Kurozu-An (鶏と野菜の黒酢あん), using black rice vinegar (黒酢, Kurozu) in the sweet and sour sauce. Black rice vinegar is an aged vinegar made from rice and it is less sour and has a deeper flavor compared to regular rice vinegar. Also, their version of sweet and sour sauce omits ketchup so you don’t see the typical red color in the sauce.

This sweet and sour chicken has been my favorite from Ootoya’s menu since I tried this dish for the first time years and years ago. When I was in Japan last summer, I shared a picture of this dish while dining there on Instagram. @alisasakura from Australia left a comment on my picture saying that Ootoya actually sells a pre-made package of this special Kurozu-An sauce. So the next time I passed by the restaurant, I bought two packages to try at home (thank you again, @alisasakura!).

Packaged vs. Homemade Sweet and Sour Chicken

After coming back to the US, I made this dish at home with the packaged sauce and tried to recreate this flavor. While testing my own recipe, I found out Ootoya actually shares the recipe for this dish online! So I made 3 batches for the taste test:

1. The recipe made with Ootoya’s package sauce
2. Follow Ootoya’s recipe to make the sauce
3. My version of Ootoya’s sauce

Our family had a serious tasting session for this recipe and one sauce won everyone’s votes for the best flavor. It was actually mine! My version was not that different from the original sauce, but in my humble opinion, I think mine has a better balance than the packaged one or the Ootoya’s recipe. However, I still think the restaurant serves the best Tori Kurozu-An, but for home cooking, my family agrees that my recipe below was the best. I wrote down the exact measurements I used so please try to be accurate for the best result.

Before sharing the video and recipe, I want to quickly mention a Japanese cooking technique called Suage (素揚げ, Su-Ah-geh). It means deep-frying without a coating of flour or batter. This technique is used mostly for vegetables (but sometimes meat too). By deep-frying vegetables for a short period of time, you can keep the crispness of the vegetable. Stir-frying vegetables take longer and sometimes the vegetables are cooked unevenly or tend to be wilted and soft. Suage technique helps the ingredient keep its original flavor, color, and shape.

Instructions

 

• Gather all the ingredients.
  
• Make the marinade. Grate the ginger and garlic. Combine the ginger, garlic, soy sauce and sake in a large bowl.
  
  
• Trim off and discard any excess fat from the chicken, then cut the meat into bite size pieces and add them to the marinade. Cover and refrigerate for 10 min.
  
  
• Combine all the ingredients for Black Vinegar Sauce and mix well together.
  
  
• Cut the potato in half and carrot into small pieces. For the carrot, I use the "rangiri" cutting technique to create more surface space so that they will cook faster and look pretty.
  
• Potatoes and carrots take too long to deep fry; therefore we boil them first for 10 minutes until they are tender. Drain and set aside.
  
  
• Cut the lotus root to ⅛" (3 mm) slices and eggplant into ½” (1.3 cm) slices.
  
• Cut onion and green peppers in wedges and cut half in length-wise.
  
  
• In a deep fryer or heavy-bottomed pot, add 3 cups of oil. Depending on the size of your pot, you will need more or less oil to have at least 2 inches (5 cm) of oil in the pot. If you are new to deep-frying, read the post about how to deep fry here. Preheat the oil to 340ºF (170ºC). Using a paper towel, pat dry the vegetables before you add them to the oil. Deep fry until they’re tender. Be careful not to over/under cook. When they’re done, drain the oil on a wire rack or paper towel.
  
• Next, coat the chicken in potato starch and deep fry at 340ºF (170ºC) for 5 minutes or until golden brown. If the chicken is being browned too quickly, adjust the heat and make sure the chicken is cooked through. Drain the oil well on a wire rack or paper towel.
  
• When the chicken is done deep frying, heat the wok and toss the deep-fried vegetables and chicken together. When they are re-heated evenly, pour the Black Vinegar Sauce over the chicken and vegetables, toss and combine. Transfer to a plate and serve.
  

To Store

• You can keep the leftovers in an airtight container and store in the refrigerator for up to 3 days.
