Preparation:
Line a baking sheet with plastic wrap. Wearing rubber gloves, wash cactus pears and with paper towels rub off any prickly fuzz left on skin. Halve cactus pears lengthwise and with a spoon carefully scoop flesh with seeds into a blender, leaving thick shells intact. Add syrup and lime juice to blender and puree until smooth. Pour cactus-pear puree through a fine sieve into a bowl and discard seeds. Put cactus shells on baking sheet and freeze while making sorbet.
Freeze puree in an ice-cream maker. Scoop sorbet into frozen shells, smoothing surfaces so they are level. Freeze filled cactus shells at least 6 hours, or until frozen hard. Frozen sorbets in shells may be wrapped individually in plastic wrap and kept in freezer 1 week. |
