A flour or sugar shaker is quite a versatile utensil. It can be used to dust icing sugar over baked goods (think brownies, cakes, pastries), or sprinkle cocoa or powdered chocolate on coffees or tiramisu. It could be used to cover freshly baked doughnuts in a cinnamon sugar - and in a pinch, it could be used as a very small sieve for flour. Wow, a dazzling amount of uses.
