Water is a simple inorganic compound consisting of hydrogen and oxygen molecules (H₂O) in liquid form. It is essential to all known forms of life and serves as the universal solvent in cooking. In culinary applications, water acts as a medium for cooking, dissolving, and hydrating ingredients, and its purity, mineral content, and temperature significantly affect the outcome of recipes. Hard water (high in minerals like calcium and magnesium) and soft water (low in minerals) can influence everything from pasta texture to the browning of baked goods.

Water is fundamental to nearly all cooking methods—boiling grains and legumes, steaming vegetables, preparing stocks and broths, making doughs and batters, and dissolving dry ingredients. It is used in sauces, soups, and stews as a base or thinning agent, and in baking to develop gluten and activate leavening agents. Water quality matters: chlorinated tap water may affect flavor, while mineral content influences cooking times and results. Temperature control is critical—cold water for rinsing and hydrating, hot water for extraction and rapid cooking, and room-temperature water for yeast activation and some dough work.
