3.  After you scrub each mussel, take a paper towel, use it[,] grasp the beard, and gently pull it toward the hinged side of the mussel to remove it.  If you tug in the other direction, you risk pulling out part of the mussel along with the beard and killing it.  If this happens, throw it away.

4. To remove the beard, hold the mussel in one hand, cover the other hand with a dry towel, and grasp the beard; give it a sharp yank toward the hinge end of the mussel. This method will not kill the mussel. If you were to pull the beard out towards the opening end of the mussel you can tear the mussel, killing it. Discard the byssal threads.

How to Debeard Mussels

Like most fresh shellfish, mussels may still have sand or barnacles on them, so wash them well before cooking. Many may also have a bristly thread called a beard, which helps anchor them to rocks in the ocean. To remove it, grasp it with your fingers or pliers and pull it toward the small end of the shell — the beards should detach easily. Just be sure to wait and remove the beards until just before serving, so the mussels don’t die in the process.
