Cut and discard stems from artichokes, making sure bottoms of each artichoke are flat. Cut and discard top 1 inch (or so) of each artichoke. Snip thorny ends from each artichoke leaf with a pair of kitchen scissors.

Fill bottom of a pot with about 2 inches of water; add lemon, garlic, and bay leaf. Place a steamer basket in the pot, making sure the water does not flow over the bottom of the steamer basket.

Place artichokes in the basket, resting on flattened bottoms.

Bring water to a boil, cover the pot, and cook until leaves can be easily pulled from artichokes, 20 to 30 minutes.
