The guys picked these tunas (cactus fruit)
Then I made them into jelly the way a friend taught me to. But first, we scooped out the insides:
They are covered with teeny, hairlike thorns my friend calls “itch-all-nights.” I tried to handle the tunas with only tongs and a dishtowel. Dang! those things hurt. The guy used all sorts of equipment, including rubber gloves, leather garden gloves, tongs, and, I think, the witchblade. I cooked the the pulp, strained the juice, and made it into beautiful magenta colored jelly.
