Water is a colorless, odorless liquid compound of hydrogen and oxygen (H₂O) that exists in all three states of matter on Earth. In culinary contexts, water serves as a universal solvent and medium for cooking, dissolving, and hydrating ingredients. The quality, mineral content, and temperature of water significantly affect cooking outcomes, from the texture of pasta to the crumb structure of baked goods. Tap water, filtered water, and mineral water each impart different properties to dishes.

Water is fundamental to virtually all cooking methods—boiling, steaming, poaching, braising, and simmering. It is essential for hydrating grains and legumes, creating stocks and broths, preparing doughs and batters, and dissolving ingredients such as salt and sugar. In baking, water controls gluten development and dough consistency; in fermentation, it enables microbial activity. Different temperatures of water serve distinct purposes: ice-cold water for chilling, room-temperature for mixing, and boiling for cooking and pasteurization.
