Why do people like duck sauce?!
Answers:
Duck sauce is a condiment with a sweet and sour flavor and a translucent orange appearance similar to a thin jelly that is used by some Chinese-American restaurants. In the New England area it is usually light brown and is commonly made from apples. It may be used as a dip for deep-fried dishes such as duck, chicken, fish, spring rolls, egg rolls, or with rice or noodles. It is often offered in plastic packets along with soy sauce and red chili powder.
