Kung Pao Sauce
from https://www.chinasichuanfood.com/

Kung pao sauce is one of the popular home style stir fry sauces in Szechuan cuisine.

Kung pao sauce has two layers of flavor, one is from spices and the other one is from a balance via soy sauce, vinegar and sugar. Firstly, we fry garlic, ginger and scallion with dried red pepper. This taste is called as “胡辣味”，which means fried chili pepper taste. To get this unique taste, the dried chili pepper should be fried until dark red. Some restaurants add un-fried red chili pepper to add some red color but they cannot bring the right flavor.

The second layer is a balanced sauce made from sugar, vinegar and soy sauce with starch. Starch works as a thickener and help the sauce sticking to the ingredient.

Important ingredients introductions

Leek onion (大葱) is a popular aromatic ingredient for lots of Chinese stir fries and soups. Comparing with green onion, leek onion provides a stronger flavor. We usually use the white part and discard the very green part and then cut them into sections around 1.5 cm in thickness. I love to keep half of the leek onion sections to the last step and fry them with chili pepper and Szechuan peppercorn.

Szechuan pepper and dried chili pepper: Szechuan peppercorn (花椒) and dried red chili pepper are the two soul ingredients for this dish. It should be a slightly numbing with a gentle touch of hotness. We have three types of dried red pepper used in Sichuan cuisine, but the most popular choice for Kung pao chicken is that small and thin pepper.

The mischievous factor of this sauce is the amount of sugar. I usually add more sugar with protein dishes but use only use half of the sugar in vegetable kong pao dishes like cauliflower, lotus root and mushrooms. Because vegetables and mushrooms have nature sweetness.

This recipe is enough for 2 servings of Kung Pao (2 chicken legs or about 1/2 pound shrimp). See Kung Pao Chicken, for instance.
