This dessert is a refreshing way to conclude a spicy southwestern meal. For a festive note, dip the rims of frozen Margarita glasses into water and then into a bowl of sugar. Attach a lime slice to the lip of the glass and fill with sorbet.
Note:
If you do not have an ice cream maker, you can turn this mixture into a granita — an Italian frozen dessert. Mix an additional 1 cup water into sorbet mixture. Freeze in bowl until semifirm, whisking occasionally, about 3 hours. Cover and freeze until solid, at least 6 hours or overnight. Using fork, scrape surface of granita to form crystals. Scoop crystals into frozen glasses and serve granita immediately.
