Keep dipping the squares of ganache — once you're in the flow of dipping the chocolates, you might find it easiest to pick up the ganache squares with your non-dipping hand and feed them to your dipping hand as you go. Keep an eye on the tempered chocolate to make sure it stays in temper. Continue to stir the chocolate as you dip. If the chocolate cools too much, turns matte, and begins to thicken, place the bottom of the bowl back into the hot water for 1 or 2 seconds. Remove quickly and stir the warmer chocolate up from the bottom and throughout the bowl. Test to be sure it has not gotten too hot and resume dipping.
