Sha cha sauce 沙茶酱 (shā chá jiàng)

Not to be confused with Thai satay peanut sauce, Chinese sha cha sauce is made with ground soybeans, garlic, and brill fish. The sauce is used by Fujianese and Taiwanese cooks to infuse soup broth with a sweet and savory flavor. Make sure you stir the sha cha sauce in the jar well before spooning it out, as the ingredients have a tendency to separate between uses. It is also called sa cha sauce, and you can find it at any Asian grocery store.
