Sweet and sour dishes are a staple of Chinese-American cooking, but sweet and sour sauce is also a delicious savory dipping companion to foods like meatballs. You can use this sauce to glaze fried nuggets of chicken or pork, or pour it over stir-fried meats and veggies.
Whisk first five ingredients and 3/4 cup of the water in a small saucepan. Bring to a boil while whisking. Reduce heat to low, and let mixture simmer for a few minutes. Dissolve cornstarch in the remaining water and whisk until smooth. Add dissolved cornstarch to saucepan and whisk. Continue whisking and cooking sauce over low heat until it's thickened, about three minutes. Store leftovers covered in the refrigerator.
