Use a silicone spatula to mix the sugar and tincture thoroughly, coating the sugar. The mixture will resemble wet sand.
Cover the dish with a layer of cheesecloth to keep dust, cat hair, fairies, and other debris out of your sugar.
Place the dish somewhere it won’t be disturbed and allow the alcohol to evaporate completely. Stir frequently (5-6 times a day) to ensure complete evaporation. If you’re looking to speed up evaporation, keep in mind that alcohol is EXTREMELY flammable. I use a heat mat for seedlings underneath my baking dish as a source of low heat to speed up evaporation.
The sugar is ready when it again looks like dry sugar, and it no longer smells like alcohol.
Store in an air-tight container in a cool, dark place.
