What is superfine sugar and can I use something instead?
Tracy R., Wayne, PA Superfine sugar is granulated sugar ground so fine it “dissolves” almost instantly in cold liquid. Regular granulated sugar needs heat to dissolve it. Instant or superfine sugar is an advantage in recipes such as a berry fruit salad where you want the sweetness without the granulated texture of sugar. Confectioner’s sugar is an acceptable substitute in some instances where the cornstarch added to the confectioner’s sugar isn’t intrusive. You can simulate a superfine sugar by whirling regular sugar in a food processor until it is more finely granulated.
