Clean artichoke by first rinsing, then cutting off stem and top. Rub top with half a lemon and place in a pot with the lemon and some more juice if desired. Fill pot so that the artichokes are half submerged.
Cook for 30-45 min. or until heart is tender. Serve with melted butter flavored to taste with lemon juice. Work your way through the artichoke leaf by leaf, dipping in the lemon butter, until you reach the "choke". Clean out the choke and enjoy the heart.
