Raisin Butter is a nostalgic appetizer in Japan during the 1970s and 1980s. It’s a simple mixture of butter and raisins shaped into a log, which is then cut into thin rounds. The raisins add sweetness and a chewy texture to the butter, creating a flavorful and slightly fruity appetizer. The slices of raisin butter were enjoyed either by itself or with crackers, often paired with alcoholic drinks, particularly whisky and brandy. Placing sliced portions of raisin butter on top of crushed ice used to be the popular style, and it was often served almost exclusively for adults due to its strong association with alcoholic drinks.
