Spread sugar out on a baking sheet and let it air dry for an hour or so, in a low humidity environment (February and March is perfect when the heat is on). Once the sugar has dried a bit, run some of the larger chunks through your food processor to break them up.
One quart (1 liter) of syrup yields about 2 pounds ( 1 kilogram), or one quart, of granulated sugar.
Pour the sugar into an airtight container, we use mason jars with the two part lid and store at room temperature.
