Hard sauce
From Wikipedia, the free encyclopedia
Hard sauce is a cold dessert sauce made by creaming or beating butter and sugar with rum, brandy, whiskey, vanilla or other flavoring. It is typically served with plum pudding, bread pudding, Indian pudding, hasty pudding, and other heavy puddings as well as with fruitcakes and gingerbread.
Though it is called a sauce, it is not liquid or smooth.
