No, not yet on the thorns (and honestly, I'm kind of done with them, the payoff was too low). 

My method was to pick them with tongs, then dump them in the sink and, wearing rubber gloves, scrub them with a brush to get the micro-spines off. That seemed pretty fool-proof.

I’ve tried foraging prickly pears too and I know how poorly that can go. Have you gotten thorns in your mouth yet?

I haven’t learned the local mushrooms here yet, but it’s on my to do list.

Daily Health Principles: Foraging for Xenohormesis

Mostly blackberries, at my previous locations, and occasionally some chanterelle mushrooms. 

Even though I'm carnivore, foraging is one area where I will make an exception occasionally. But where I'm at now, there's not much opportunity to forage. There's tons of prickly pear cactus fruit, but though they look beautiful, they're just not very flavorful at all. And it's a massive pain to get the thorns off.
