Crush the cardamom pods open so the little black seeds come out, crush the seeds lightly. Chop the chocolate into small pieces and place in a bowl. Bring the cream and cardamom to boil, pour through a fine sieve over the chocolate, stir until the chocolate is melted. Add butter and whiskey, stir until smooth and shiny. Chill for at least 4 ours, preferably over night.
Dust your hands lightly with cocoa powder and roll teaspoons of the truffle mix into little balls. Chill for 1 hours. Melt the chocolate and roll each truffle in the chocolate until the surface is covered, roll in cocoa powder and chill. Keep in the fridge in an air tight container.
