Raisins are dried grapes produced primarily from seedless varieties of Vitis vinifera, a species native to the Mediterranean region and Central Asia. The drying process concentrates sugars and develops a chewy texture and complex sweet-tart flavor profile. Raisins can be produced through sun-drying (the most common method, particularly in California and the Mediterranean), mechanical dehydration, or shade-drying, each method imparting subtle differences in color and flavor. The primary varieties used include Thompson Seedless, Flame Seedless, and Black Corinth, which range in color from golden to dark brown to deep purple.

California's San Joaquin Valley produces approximately 99% of the United States' raisin supply, while significant commercial production also occurs in Turkey, Greece, Iran, and Australia. Raisins contain roughly 15% of their original water content, making them shelf-stable and nutritionally concentrated.

Raisins function as both a sweetening agent and textural component across diverse culinary applications. In baked goods—including breads, cakes, cookies, and pastries—they provide natural moisture, sweetness, and chewy texture. They are essential in traditional puddings, grain pilafs (particularly in Middle Eastern and Indian cuisines), and couscous dishes. Raisins feature prominently in savory applications such as Moroccan tagines, Spanish paellas, and Indian biryanis, where their sweetness balances spiced or meat-based components. They are also used in breakfast cereals, trail mixes, and granolas. Soaking raisins in warm liquid before use hydrates them and can be added to sauces or marinades for depth of flavor.
