A measuring cup is a kitchen tool used to measure liquid or dry ingredients accurately. It typically has graduated markings on the side, indicating various volume measurements, such as cups, ounces, or milliliters. Measuring cups can be made from materials like glass, plastic, or metal, and they come in different sizes to accommodate various cooking and baking needs. In cooking, precise measurements are essential for achieving the desired taste and texture of a dish. Using a measuring cup helps ensure that ingredients like flour, sugar, or water are added in the correct amounts, which is especially important in recipes involving chemical reactions, such as those found in baking with baking powder or yeast.
