Duck sauce, also known as orange sauce, is a sweet and sour seasoning with a transparent orange color comparable to a thin jelly. It's served as a dip with deep-fried meals including wonton strips, spring rolls, egg rolls, duck, chicken, and fish, or with rice or noodles at American Chinese restaurants. It may be used as a glaze over meals like poultry. The sauce is not made using duck flesh, instead, it is called after the Chinese-style duck dishes to which it is commonly served.
