When you buy chocolate molds from the craft store, make sure that this is made from strong plastic that has intricate designs so the finished product will come out beautifully after it comes out of the freezer.
Remember that this must never be washed using soap as this can mare the taste of the chocolate. You should simply use hot water and then dry it thoroughly using a dry cloth.
Each time you use the plastic mold, make sure to wipe it clean. Greasing, spraying or dusting is not needed as this will ruin the appearance of the finished candy.
