Rimming the Glass

Because you need a fine powder, it is necessary to use a mini food processor or a clean coffee-type grinder (reserve one for spices only—otherwise your coffee will flavor your spices and vice versa). Pour the finished mixture onto a small, curved dish, such as a saucer. Wipe just the edge of the glass with a wedge of lime or lemon and dip the moistened edge into the powder, to lightly coat the glass. (The dusts may also be sprinkled on the rim.) Don’t overdo it—a light dusting is best. You can also dust just the inside rim of the glass; see the Margarita SOL.
