Add tempered chocolate to the silicone molds. 1 heaping teaspoon per mold cavity, depending on the size of your molds. Pay attention to the edges and make sure they are nice and thick.

Remove set molds from the fridge. Add another layer of chocolate, ensuring the edges are nice and thick.

Remove from fridge and remove chocolate half spheres from the molds.
Heat a plate or a frying pan on low. Warm the edges of a half sphere, just until it melts.
