.5 ml water

Water is the chemical compound H₂O, consisting of hydrogen and oxygen atoms in a 2:1 ratio. In culinary contexts, water refers to the clear, odorless, tasteless liquid essential to cooking and food preparation. Water exists as a universal solvent in the kitchen, dissolving salts, sugars, and other solutes; hydrating grains, legumes, and pasta; and serving as the medium for extracting flavors through steeping, boiling, and braising. The quality and mineral content of water—influenced by geographical origin and treatment—can significantly affect cooking outcomes, from the texture of bread dough to the color of blanched vegetables and the flavor of tea and coffee.

Water is the foundational liquid in virtually all culinary traditions, used to cook grains and legumes, prepare stocks and broths, blanch vegetables, and rehydrate dried ingredients. It serves as the primary ingredient in soups, sauces, and braised dishes, and is essential for dough preparation in baking and pasta-making. Water's role extends to temperature control during cooking, steaming, poaching, and the creation of syrups and glazes. The mineral content of water—hardness or softness—can influence extraction in tea and coffee brewing, the setting of gelatin-based desserts, and the texture of baked goods.
