USE your fingers to pull off the rest of the tough leaves and discard. You can leave the very delicate inner leaves in place.4. USE a vegetable peeler or paring knife to peel away the stem’s tough outer fibers, as well as any tough-feeling parts around the base.5. SLICE the artichoke right down the middle, stem and all.6. REMOVE the choke by using a small spoon (a melon spoon works best, but any small spoon will do) to scrape out the fuzzy white center of each artichoke half. Discard.7.
