Step 5 Mold Prep

I won't go into making custom molds, I recommend the following instructable for that:

However, I do recommend using food grade silicone, as it can deal with the heat, and won't leave any nasty residue should you decide to eat your creation.

Coat the inside of the mold with either a light cooking spray (not recommended) or a light dusting of corn starch. The corn starch will also help keep the item dry longer.
