The core ingredient of green chili sauce is fresh green chilies, commonly including varieties such as Hangzhou chili, long chili, and Erjingtiao chili. Small red chilies can be added to adjust the spiciness.

Common auxiliary ingredients include garlic, ginger, onion, salt, sugar, and cooking oil (such as rapeseed oil).

Optional ingredients include white sesame seeds, fried soybeans, fermented black beans, Sichuan peppercorns or green Sichuan peppercorns, light soy sauce, vinegar, chicken bouillon, and oyster sauce to enrich the flavor and texture.

When selecting green chilies, choose varieties with thick flesh, moderate moisture content, vibrant color, and smooth skin; ensure that garlic, ginger, and other auxiliary ingredients are fresh and free from spoilage.

All ingredients must be thoroughly washed with running water before processing and air-dried or wiped dry to prevent the sauce from spoiling during storage due to the introduction of raw water.
