Table sugar that’s processed into smaller granules is called superfine. The result is a sandier sugar that’s usually used for finishing. It’s the sugar you’ll find on doughnuts, pie crusts, and sugar cookies. It can be used in place of white sugar, too. If you’re looking to add sugar to a rub, this one will better melt into meat’s natural juices and ensure a caramel-glaze when it cooks.
