Chili oil is a simple oil used in Asian cuisine, particularly in Chinese and Thai cooking. Although the ingredients used vary somewhat by region, most types of chili oil are made from chili peppers soaked in oil such as olive, soybean or canola oil 3. The oil is sometimes heated slowly at about 180 degrees F for two or three hours to allow the it to more effectively soak up the heat and flavor of the peppers. Chili oil can be refrigerated for up to one month, according to the Food Network website 1.
