I wouldn’t dream of visiting the vast Central Market in Florence without my friend Judy Witts, known throughout town as the Divina Cucina. With Judy as my guide, butchers and cheese merchants greet us like given-up-for-lost family members, and everywhere we turn another oversized platter appears, heaped with Tuscan delights: sheep’s-milk pecorino, candied fruits spiced with mustard seeds, fresh raspberries dotted with syrupy balsamic vinegar, and, gulp, juicy tripe sandwiches (which I haven’t built up the courage to try). And because we’re in Italy, it all ends with shots of grappa taken straight from little glass vials, obbligatorio after all that sampling. This sorbetto is adapted from Judy’s recipe. One of her favorite parts is the little chocolate “seeds” it contains. Since watermelons have a lot of water, take the sorbetto out of the freezer long enough ahead of serving to make it scoopable, 5 to 10 minutes. To pass the time, serve shots of grappa, and if there’s any left by serving time, splash some over the sorbetto too.
I find that I get about 3 cups (750 ml) of watermelon juice from a 3-pound (1 1/2-kg) chunk of watermelon. Cut away the rind, remove any seeds, and then cut the juicy, pink flesh into cubes and purée them in a blender or food processor. Any extra juice can be frozen for another use, such as watermelon margaritas.
