Casting Chocolate Molds
Working with molds is how you move from merely melting chocolate to shaping it. The goal is a uniform shell that releases cleanly from the plastic without leaving streaks or stubborn spots behind.
Cleanliness is your primary tool
Even a microscopic speck of water or dust will ruin the finish, leaving spots or preventing the mold from releasing. Ensure your molds are polished with a dry lint-free cloth before starting.

Mastering the Temper
Chocolate must be brought through a specific heat cycle to align its cocoa butter crystals. If you skip this, your pieces will remain soft, bloom white after a few days, and stick to the mold.
The method.
Prepare the molds
Buff each cavity with a clean microfiber cloth until it reflects like a mirror. Do not use soap or water unless absolutely necessary, and if you do, ensure they are bone-dry before beginning.
Temper the chocolate
Melt your chocolate to 115°F, then cool it down by stirring in 'seed' chocolate until it drops to 82°F. Gently reheat it to the working temperature of 88-90°F.
Fill the molds
Ladle the chocolate into the cavities. Pick up the mold and tap it firmly against the counter ten times. This vibration brings trapped air to the surface.
Scrape and set
Use your offset spatula to pull one single, smooth stroke across the top of the mold to remove excess chocolate. Leave it in a cool, dry room—not the refrigerator—until the chocolate loses its gloss and releases from the sides.
When it doesn't go to plan.
If your chocolate isn't releasing, it isn't set yet; be patient rather than forcing it.
Avoid high humidity; moisture in the air can make the chocolate seize.
Use a marble slab for cooling if you have one, as it pulls heat away from the chocolate efficiently.
The ones that keep coming up.
Can I use chocolate chips from the grocery store?
Avoid them. They contain stabilizers that prevent them from melting smoothly or tempering correctly.
Why is my chocolate cloudy?
This usually indicates the chocolate was not in temper or the mold was not clean/polished prior to filling.
