We tested this recipe with Lindt, Valrhona, Ghirardelli, and Callebaut bittersweet chocolates, all of which worked equally well. Our favorite, however, was Valrhona, which made for an especially rich-flavored gianduia.

For this recipe you will need heavy-duty foil (thicker and wider than regular foil) to waterproof the springform pan.
