The term BLACKEN WITH FIRE can be summarized as the process of charring something with fire. Charring is a cooking technique that involves exposing food to direct, high heat for a short period of time in order to create a smoky flavor and a crispy texture. Charring is often used to cook meats, vegetables, and fruits. Charring is also used to blacken the surface of certain materials, such as wood or metal, by burning them with an open flame.
