Creamy Cashew Frosting

After the cashews and dates have soaked, remove them from the water and place them into a high-speed blender or food processor along with the 1/2 cup water. Blend until mixture is smooth and creamy (add tiny amounts of water as needed). If you would like a lemon flavor, replace 1/4 cup water with 1/4 cup lemon juice. (Meyer lemons, a cross between a true lemon and either a mandarin or common orange, have a great flavor.)
