Wear gloves! This is not a suggestion—it’s a plea. Cayenne oil will get on your fingers, and the next time you rub your eye or touch a sensitive area, you will deeply regret it. Ask me how I know.
Also, don’t get the powder airborne. When you open the grinder, let the dust settle for a few seconds. Otherwise, you’ll have a pepper gas attack that clears the room faster than a bad joke.
