Keeps several weeks at room temperature when stored in a cool, dry place, under a bed of powdered sugar.
TIP: Sometimes thermometers are slightly off. Because of this, my Turkish Delight came out rather soft. To avoid this, drop some of the sugar mixture into cold water. When it cools off, bite it. If it has the texture of a chewy ball, you are on track.
OPTION: You can just use one casserole and layer your two flavors on top of each other to make multicolored llokume. They will be twice as thick, however.
