A colander is a kitchen utensil designed for draining liquids from solid foods. It typically consists of a bowl-shaped container made of materials like stainless steel, plastic, or aluminum, with evenly spaced holes or perforations on the sides and bottom. Colanders come in various sizes and shapes, including the classic bowl shape with handles or the more modern collapsible versions for easy storage. They are primarily used for rinsing and draining foods like pasta, vegetables, fruits, or cooked grains, allowing the liquid to pass through while retaining the solids. Colanders are an essential tool in the kitchen, helping to separate and prepare ingredients for cooking, salads, and other culinary preparations while making the process of draining and washing more efficient and convenient.
