Cut the ganache: While your bowl of tempered chocolate is cooling, cut the ganache into squares. Use a sharp knife, run it under hot water to warm it up and then dry it thoroughly. Do this in between each cut. The size is up to you, but on average, go for 1-inch x 1-inch squares for a two-bite piece of chocolate. Return the cut ganache to the refrigerator. Keep an eye on the cooling chocolate as you prepare the ganache, occasionally stirring and testing the chocolate beneath your lower lip
