Trim the baby artichokes: Pull off and discard the green outer leaves.
Eventually you will come to a point where the leaves are tender and
soft, half green and half yellow. Use a sharp, heavy knife to cut off
the top (green) portion of the vegetable, where the yellow meets the
green. Slice the stem level with the base and trim off any wayward
leaves from the base. Slice the artichoke in half lengthwise. Use a
small knife to remove any purplish leaves or any bits of fuzz. Place
the artichoke halves in the lemon water.
