⅓ cup water

Water is a colorless, odorless, and tasteless liquid compound of hydrogen and oxygen (H₂O) that occurs naturally on Earth and is essential to all known forms of life. In culinary contexts, water serves as a universal solvent and medium for cooking, dissolving, and combining ingredients. The quality and mineral content of water can vary significantly by source—tap water, filtered water, distilled water, and mineral water each possess different properties that may affect cooking outcomes, particularly in baking, brewing, and the preparation of stocks and broths.

Water is fundamental to cooking across all culinary traditions, functioning as a cooking medium for boiling, steaming, and poaching; a solvent for dissolving salt, sugar, and other ingredients; and a hydrating agent in doughs, batters, and sauces. It is essential in stock and broth preparation, where its capacity to extract and suspend flavors from bones, vegetables, and aromatics creates the foundation for countless dishes. In baking, water hydrates flour and activates gluten development, while in beverages—from coffee and tea to stocks and soups—water's properties as a universal solvent are paramount.
