Set a steamer basket over rapidly simmering water with 1/2 lemon, a few parsley stems and 2 smashed garlic cloves in the water. Trim 4 large artichokes, removing the stems. Stand upright in the basket. Cover and steam over medium heat, adding more water as needed, until tender, about 45 minutes. Serve with melted butter for dipping.
