Rimming sugar
From Wikipedia, the free encyclopedia
Rimming sugar is a sugar-based preparation used to decorate and flavor the rims of cocktail glasses. Rimming sugar is often flavored with fruit juice, spices or other flavorings, and different varieties are best suited to different cocktails. It is typically sold in round tins sized to allow the top of the glass to be placed upside down into the sugar in the tin.
Contrary to innuendo, rimming sugar is not any way connected with the sexual activity of rimming.
