Wear leather gloves to prepare a prickly pear. It has both long spines and shorter, hairlike spines that will dig into your skin.
Scrape the edge of a sharp knife along the fruit to remove the large spines.
Peel the skin off with a vegetable peeler or your knife. This will get rid of any remaining thin spines. Rinse carefully to wash away any spines that may have stuck to the fruit.
Eat the fruit raw by itself, if you prefer, or slice it to add to a fruit salad. The seeds are edible. Dice the prickly pear fruit and use it as a topping for cereals, omelets or even ice cream.
Add chopped prickly pear fruit to a blender along with plain yogurt to make a smoothie, or blend it with vanilla ice cream to make a milkshake. Another option is to squeeze the juice of the prickly pear into beverages to add a fruity flavor.
