Nutella

Nutella, a chocolate hazelnut spread, makes these the panini that kids love best. Since they're as simple as a peanut butter sandwich to prepare, our son Jack helps us make them for his playmate friends. This traditional Italian snack is as compelling for grown-ups as it is for their kids.

We used store-bought graham cracker crumbs to save time; if you prefer to make your own in a food processor, you'll need 13 crackers, each about 4 3/4 by 2 1/4 inches. Freezing the tart helps to chill it quickly. If you're not in a rush, simply chill the tart in the refrigerator until you're ready to serve it.

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.

Gianduia is a classic Italian combination of chocolate and hazelnuts. If you can't find foil candy cups, buy twice as many paper ones and use two (one inside the other) per candy. (Doubling the paper cups makes a sturdier form.) Arrange the confections in holiday tins, or place on decorative trays, wrap in cellophane and tie with gold ribbons.
