Raisins / Sultanas

Raisins are dried grapes from Vitis vinifera, a fruit that transforms dramatically through dehydration. Fresh grapes contain roughly 80% water; when dried, they lose most of that moisture, concentrating sugars and creating the chewy, wrinkled texture we recognize. This concentration means raisins pack intense sweetness into a small volume, making them one of the most efficient natural sweeteners available. The transformation from grape to raisin also develops complex caramel and fruit notes that fresh grapes lack.

The term 'raisin' is broad, encompassing several processing methods and grape varieties. Thompson Seedless grapes produce the dark, wrinkled raisins most common in North American markets. Sultanas—sometimes called golden raisins—come specifically from white Thompson Seedless grapes and receive sulfur dioxide treatment to preserve their pale color and mild, almost honeyed flavor. Currants, despite often being grouped with raisins, come from a different grape variety (Corinth) and are significantly smaller and more intensely sweet. Understanding these distinctions matters: a recipe calling for currants will not achieve the same result with standard raisins due to size and sweetness differences.

Raisins behave predictably in cooking: they rehydrate readily when soaked in liquid, they absorb flavors from their soaking medium, and they add sweetness and textural contrast to both sweet and savory dishes. Their high sugar content acts as a preservative, contributing to their excellent shelf stability. In baking, raisins provide pockets of sweetness and moisture; in savory dishes like tagines or pilafs, they offer balance against acidic and spiced elements. The key to working with raisins is understanding that they continue interacting with moisture throughout cooking—adding them early means they swell and often dissolve; adding them late preserves their distinct chewy character.
