Martinique Swizzle

Squeeze lime juice into 14-ounce chimney glass filled with shaved ice; save shell. Add remaining ingredients. Swizzle until drink is uniform. Decorate with spent lime shell, fresh mint, and a long stirrer. 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.
