Knocking out the spent espresso puck from the portafilter is oddly satisfying, but proper prep starts before you tamp. You want a level, even dose of freshly ground coffee, not overfilled, with no stray grounds on the rim. Distributing with a gentle tap or a leveling tool helps ensure the puck's density is uniform. That way, your tamp is a final, firm press that sets the stage for even extraction and a clean, uniform puck when you're done.
