A large, deep bowl used for combining ingredients during food preparation. Mixing bowls come in stainless steel, glass, ceramic, and plastic, in nested sets of graduated sizes. A good bowl has enough capacity to toss salads, mix batters, or knead small doughs without spilling, with a stable base and comfortable grip. Stainless steel is light and durable for whisking, glass allows visibility and suits microwaving, and ceramic offers weight and attractive serving. Every kitchen needs several: one for every stage of a recipe keeps preparation organised. Wide, shallow shapes suit tossing, while deep ones contain vigorous beating.
