4 lb ripe watermelon, cantaloupe, or other sweet melon, seeded and rind removed, or 6 cups berries, stemmed if necessary, or 6 ripe mangos, peeled and pulp cut of the seeded
½ cup superfine sugar, depending on the fruit sweetness
3 tbsp tequila (optional ; see note )
Recipe
Purée the fruit in a food processor. Transfer the puree to a large bowl. Stir in sugar to taste and the tequila, if using. Mix well to dissolve the sugar. Place the mixture in the freezer and chill until it begins to freeze around the edges and across the top, about 2 hours.
Whisk to break up and mix in the ice crystals, then return to the freezer and chill for 2 hours more.
Whisk again, breaking up the ice crystals and remixing into an evenly granulated mix. Cover with plastic wrap and return to freezer until frozen through, 2 - 3 hours more or up to several days.
Remove from the freezer 45 minutes before serving so the ice softens enough to spoon out.
Cooks note : Tequila does more than add flavor. The alcohol prevents the mixture from freezing so solid that you cant spoon it out without completely defrosting it.
