Pour 2 cups of water into an 8-quart pot, cover, and bring to a boil. Scoop the clams into the pot and steam, covered, for 4 minutes. Remove the lid and gently stir the clams with a wooden spoon.☞ TESTER TIP: The clam shells are very brittle, so stir carefully!
Cover and continue steaming until all the clams open, 4 to 6 minutes. Discard any clams that don't open.
