Hoisin sauce, or Haixian Sauce, is a Chinese dipping sauce.
The word Hoisin is a romanization of the Chinese word for seafood as
pronounced in Cantonese. Mandarin-style Hoisin sauce ingredients include water, sugar,
soybeans, white distilled vinegar, rice, salt, wheat flour, garlic, red chili
peppers, and several preservatives and coloring agents. Traditionally, Hoisin
sauce is made using sweet potato. Despite the literal meaning of "seafood,"
Hoisin sauce does not contain fish.
