Chili oil is a popular condiment made by infusing oil with dried chili peppers and other spices. It is commonly used in various cuisines, particularly in Chinese and Sichuan cooking, to add heat and flavor to dishes. The oil can vary in spiciness depending on the type of chili used and the infusion process. Typically, chili oil is made by heating oil, such as vegetable or sesame oil, and then adding crushed or whole chili peppers. Some recipes may also include garlic, ginger, or other seasonings to enhance the flavor. It can be drizzled over noodles, used as a dipping sauce, or incorporated into marinades.
