Preventing white sugar from clumping in the canister We store sugar in a ceramic canister, and we get some clumping. Restaurants in humid areas that will often add grains of a rice to a salt shaker to stop clumping. (The rice acts as a desiccant and absorbs moisture, keeping it away from the salt; I believe the salt also acts as a preservative for the rice.) Is there an equivalent common household item that will keep moisture away from the sugar, or is getting a better canister really the only way?
You can still add rice, just wrap it in some cheesecloth first, so it doesn't get mixed with your sugar.
