A skewer is a long, thin tool, often made of metal or wood, used to hold pieces of food together while cooking or serving. Commonly used for grilling, skewers can hold meats, vegetables, and even fruits, making them popular for dishes like kebabs and shish kebabs. They help ensure even cooking and can make food easier to eat. Skewers come in various sizes and materials, with metal skewers being reusable and wooden ones typically requiring soaking in water to prevent burning. They are a versatile kitchen tool, often used in outdoor cooking, barbecues, and even in some cooking techniques like broiling.
