Step 1

Heat cream to a simmer: In a small, heavy saucepan bring the heavy whipping cream to a simmer (stir and scrape down the sides with a spatula every few minutes).If you are using one of the other recommended flavorings, stir it in with the cream (and ignore vanilla in the next step). If adding mint or other solids, after the cream simmers, remove from heat and let seep for an hour. Then strain away solids, and return the cream to a simmer and proceed with recipe.

Step 2

Make chocolate base: Place the chocolate in a separate bowl. Pour the cream over the chocolate, add the vanilla, and allow to stand for a few minutes then stir until smooth. (This chocolate base is called ganache.)

Step 3

Refrigerate for 2 hours: Allow to cool, then place in the refrigerator for two hours.

Step 4

Roll into balls and chill overnight: Use a teaspoon to roll out balls of the ganache. Roll in your hands quickly (as it will melt from the heat of your hands) and place on a baking sheet lined with parchment paper. Place in the refrigerator overnight.

Step 5

Roll in cocoa powder: Roll in cocoa powder or chopped nuts and serve. If not using right away, keep the coated truffles covered in the refrigerator for up to 4 days. For the best flavor and texture, let the refrigerated truffles come back to room temperature before serving.
