Swizzles originated in the West Indies, where everything, including hot chocolate, is swizzled. A swizzle stick is the branch of a tropical bush with three to five forked branches on the end. You insert this in the glass or pitcher and twirl the stem rapidly between the palms of your hands. By rapid swizzling with fine ice, you'll get a good outside frost such as on a Julep. Of course you won't get this frost if you haven't used enough liquor; a generous amount of liquor is important... Most true Swizzles, because of their origin, call for rum; but nearly all punches can be swizzled. Punches for three or four people can be mixed in a pitcher with fine ice and swizzled until the pitcher frosts, and then poured into tall glasses...
