8 Prickly Pears (they call these Tuna) in Mexican markets. They come in yellow, orange and pink. My favorite is pink.
1 cup of simple syrup (half water/half sugar till sugar melts) or light agave syrup. Sometimes I put fresh mint in the syrup too.
Juice of three limes
1/4 cup raspberry liqueur such as Framboise. This step can be eliminated if you do not want the liquor.
Often times you can find these pears growing wild and in gardens. In Mexico they also candy them. In Italy they are used to make gelato ad sorbet in the fall.
When making your simple syrup, you can add spices, in this case I used one cardamom pod, mint, a cinnamon stick and 3 star anise. These just flavor the syrup slightly.
Using a fork, cut off the ends of the prickly pear. Commercial pears like you would find in a hispanic grocery will have the little prickles removed. If you harvest them your self, you will need to be more careful. Hold the fork on one end, stand the pear on the other end and using a sharp knife cut just the skin from the pear. Then cut into large chunks and place in a food processor. Pour in the simple syrup, lime and liqueur. Pulse until the mixture is smooth.
Strain carefully, there are a lot of seeds inside. Cool the mixture.
Process as you would in any ice cream or gelato machine. Pack tightly in freezer containers. It will be ready to eat within a couple of hours.
