This vinegar glazed chicken is, according to Grace Young, a typical Hunan family style stir-fry. Grace simplifies the recipe by using crushed red pepper instead of dried chilies.
One of the key ingredients in this Vinegar Glazed Chicken is Chinkiang vinegar, made from fermented rice. It's dark colored, and fairly mild and slightly sweet. If you can't find it, balsamic vinegar is a great substitute.
