c. raisins

Raisins are dried grapes (Vitis vinifera) produced by dehydrating fresh grape berries, concentrating their sugars and creating a shelf-stable preserved fruit. The primary varieties used for raisin production include Thompson Seedless grapes, which dominate global production, and Flame Seedless, Black Corinth, and Muscatel cultivars. The drying process—whether sun-cured for 2–3 weeks in vineyards or mechanically dried—transforms the grape's water content from approximately 80% to 15–16%, producing small, wrinkled, dark brown or black fruits with an intensely sweet flavor profile and chewy texture. Raisins retain the nutritional essence of grapes while concentrating natural sugars (primarily glucose and fructose), organic acids, and phenolic compounds.

Raisins function as both a sweetening agent and textural component across global cuisines. In baking, they are incorporated into breads, cakes, cookies, and pastries, where they impart moisture and concentrated sweetness. Middle Eastern and Indian cuisines employ raisins in savory preparations—rice pilafs, tagines, curries, and meat dishes—where their sweetness balances spices and creates complexity. Raisins are consumed as a standalone snack, mixed into breakfast cereals and granolas, and used in traditional puddings and compotes. They rehydrate when cooked into moist dishes or can be plumped in warm liquid before use. Their versatility derives from their dual capacity to provide natural sweetness without refined sugar and a textural contrast in both sweet and savory applications.
