Clean and scrub the clams under cold water. Drain and set aside.
Set up a skillet with butter, add the garlic, and sauté until aromatic or lightly browned. Add the clams and stir a few times before adding the beer. Then, add the pepper, lemon, and chopped parsley. Stir to combine well.
Cover the skillet with a lid and steam on high heat for 2-3 minutes, or until all the clams have opened. Serve immediately.
Notes
As clams are naturally briny, you don't need salt. If your beer broth is not salty enough, add a pinch of salt.
