What kind of fruit is dried to make raisins?

Grapes are the fruit dried to make raisins. A raisin is a grape whose water has been removed through sun-drying or controlled commercial drying.

Raisins can be made from many grape varieties, including seedless grapes. As the fruit dries, its sugars and flavors become more concentrated, which is why raisins taste much sweeter than fresh grapes. Raisins may be eaten as a snack or added to bread, cereal, desserts, salads, and savory dishes.

The names for dried grapes vary by region and variety. In many English-speaking contexts, sultanas are golden dried grapes, while Zante currants are small dried Black Corinth grapes; they are not true currants from the berry genus Ribes. Golden raisins are often treated with sulfur dioxide and dried in ways that preserve their pale color. Plums are dried to make prunes, a common mix-up with raisins.
