Raisins by John Spottiswood.

The common raisins we see on supermarket shelves are usually dried Thompson seedless grapes. Golden raisins are amber in color and somewhat tart--many cooks prefer them over ordinary raisins for baking and cooking. Muscat raisins are dark and very sweet, and they work well in fruitcakes. Currants are about one-quarter the size of ordinary raisins, and are typically used in baked goods. Store raisins in the refrigerator after you open the package.
