– 1 cup of water

Water is a colorless, odorless, and tasteless liquid composed of hydrogen and oxygen molecules (H₂O) that occurs naturally throughout the environment. It is the fundamental solvent in culinary preparation and appears in nearly every cuisine worldwide. In cooking, water serves as a medium for dissolving, cooking, and hydrating ingredients, and its quality—including mineral content, pH, and purity—can significantly influence the outcome of dishes, particularly in applications such as bread-making, sauce preparation, and tea brewing.

Water functions as the primary cooking medium in countless culinary applications: boiling pasta, rice, and vegetables; steaming; making stocks and broths; dissolving ingredients in batters and doughs; and creating sauces and gravies. It hydrates dried ingredients such as beans, grains, and mushrooms, and serves as the base for beverages including tea, coffee, and broths. The mineral content of water—whether soft or hard—affects cooking outcomes; hard water with higher mineral content can alter cooking times for legumes and affect the texture of baked goods, while distilled water is sometimes preferred for delicate preparations.
