Once the ganache is very firm, pour a little honey in the middle of each ganache circle. Then pipe more ganache on top of that, making increasingly smaller circles so that the final truffles resemble the cone shapes of beehives. It’s best to let these set in the refrigerator for about an hour to firm up, but you can speed up the process by freezing them for about 15 minutes. You don’t want to leave them in the freezer for too long, as dipping truffles that are frozen solid doesn’t produce very good results.
