Method
With a large knife, cut stems off artichokes so they sit flat on the plate. While working with one artichoke, place others in a large bowl of water and the lemon juice. This will prevent the artichokes from discoloring. Cut off top 1/3 of artichoke. Clip points off remaining bottom outer leaves. Repeat with remaining artichokes.
In a large pot, place 1-2 inches of water in the bottom with sea salt and steam artichokes for 20-30 minutes (depending on their size) until one of the leaves pulls out easily. Drain and serve upright with lemon butter sauce or chill and serve with a vinaigrette or flavored mayonnaise.
