How do you cut and prepare prickly pear cactus? Carefully. Here's a step-by-step guide with photos and recipe suggestions.
1 Slice both ends of the prickly pear off. Discard them.
2 Make one long vertical slice down the body of the prickly pear.
3 Slip your finger into the slice and grab a hold of the skin.
4 Begin to peel back the thick fleshy skin that's wrapped around the prickly pear. Discard the skin. You'll be left with the prickly pear itself. The flesh is studded with tons of little edible seeds, if you like them, feel free to just chop the prickly pear up and eat, seeds and all.
I myself prefer just the juice. To extract the juice, place the "husked" prickly pears into a blender or food processor and pulse until liquefied. Place the juice into a fine mesh sieve and push out the juice into a pitcher or bowl. Discard the remaining pulp and seeds.
Use the juice as you like. Depending on the size of the prickly pears, 6 to 12 prickly pears will get you about 1 cup of juice. It's great mixed in with some fresh lemonade, just use equal parts of prickly pear juice to lemonade.
