Plantains are a type of banana that are larger and starchier than the sweet bananas commonly eaten raw. They are typically green when unripe and turn yellow or black as they ripen. Unlike sweet bananas, plantains are usually cooked before consumption and are a staple food in many tropical regions. Plantains can be prepared in various ways, including frying, boiling, or baking. They are often used in savory dishes and can be found in cuisines across Africa, Latin America, and the Caribbean. Their versatility makes them a popular ingredient in many traditional recipes.
