How to tell if live mussels has gone bad

  • Shells gaping open that won’t close when tapped
  • A cracked or crushed shell
  • A crab that has stopped moving
  • A sulfurous smell instead of clean brine

When in doubt, throw it out.

Scrub and debeard mussels right before they go in the pot, not ahead of time — pulling the beard kills them.
