Yes, I’ve bought them several times in the past.
They’re very versatile. I love them in salad, in pasta, dip, roasted. They have a very unique taste.
Every video I’ve watched (and I’ve watched dozens) follow roughly the same process - cut the top off, break the leaves off, dig the choke out, scrape it clean, then boil it or stuff and bake it.
I want the bits that look like what come out of the jars. I’ve bought probably a dozen artichokes, and I start cutting off the tops, breaking off the leaves, and I take off more leaves, and more leaves, and then I’m left with a big pile of leaves and the fuzzy choke. I don’t know where the stuff that comes from the jars is on an actual artichoke. No one seems to get to those in any of the videos.
