This stays drier and stores wonderfully as is but even better if you spread colored salt/sugar in a thin layer to air dry for about an hour or microwave in 30 second intervals, stir and repeat for about 1-2 minutes or until moisture is evaporated. You can also add a few grains of rice to absorb any moisture. OR Baking Pan Tin Foil 1/4 cup of salt 1/2 teaspoon of food coloring Preheat an oven to 350 degrees.
