If you really want to treat the Dungeons and Dragons fan in your life (or really any game fan that uses dice), you might consider giving the gift that is right up their alley, and homemade to boot – chocolate dice.
You should really thank Ariel Segall, who has written up detailed directions on how to mold chocolate dice. It looks a little complicated for the novice, but those that know their way around mold-making and chocolatiering (I have a +8 on each) should be able to crank out several batches of these between now and the end of the week.
