Recently I managed to accidentally get a bunch of raw sugar crystals stuck to the rim of a mug of tea. Drinking the tea over the sugar, being able to balance out the tartness and the sweetness as I liked was pretty amazing. Is there an easy way to repeatedly 'stick' a bunch of sugar to the rim of a mug or glass? I know that people do this with margaritas and the like, so I assume there must be an easy technique for doing it quickly, but I don't know one.
What is the quickest/best way to do it a lot of times fast?
