White raisins are a variety of raisin that are white in colour. They are often called golden raisins or muscats. White raisins are oven dried unlike the typical sun-dried raisin. They can be eaten in place of "normal" raisins and are less sweet than sultanas. They are often used in baking such as in pies and with other fruits.
The specific golden raisin variety was made popular by Paul Harvey, who in the 1990s told listeners about a folk remedy that when dipped in gin the raisin would relieve arthritis pain. Although no actual benefits have been found from arthritis sufferers in consuming such a raisin, it is mainly the theory that supports the argument. Alcohol can indirectly relieve chronic pain through its ability to ease anxiety and depression, so it logically stands that alcohol soaked raisins would have the same effect.
