Sugar is a simple carbohydrate composed primarily of sucrose, a disaccharide derived from sugarcane (Saccharum officinarum) or sugar beets (Beta vulgaris). The plant juice is extracted, processed through crystallization, and refined to produce granulated white sugar, the most common culinary form. Sugar crystals are white to translucent, highly soluble in water, and have a distinctly sweet taste with no competing flavor notes. Various types exist along the refinement spectrum, from dark muscovado with molasses content to super-fine castor sugar designed for specific applications.

Beyond sucrose, the category encompasses other sweetening sugars including fructose (fruit sugar), glucose (dextrose), lactose (milk sugar), and maltose (malt sugar), though sucrose remains the standard sweetener in most culinary contexts. The term "sugar" without qualification typically refers to white granulated sucrose.

Sugar serves as a fundamental ingredient across all culinary traditions, functioning not merely as a sweetener but as a critical structural and functional component in cooking and baking. In baking, sugar creams with fat to incorporate air for cake structure, caramelizes to provide color and complex flavors, and attracts and retains moisture in finished goods. In confectionery, precise heating to specific temperature stages (soft ball, hard crack) creates distinct textures from fudge to pulled sugar work. Sugar balances acidity in sauces, preserves fruits through osmotic preservation, ferments into alcohol, and caramelizes when heated to create deep umami and nutty notes essential to braises, glazes, and sauces across cuisines.
