Is it OK to eat Mussels that don’t open when they’re cooked?
When cooking Mussels, there are often a few stubborn shells that don’t open regardless of how long they’re cooked. Traditional wisdom was to discarded these (as they may have already been dead prior to cooking), you can, however, pry them open away from the plate of food, and if they smell good, they’re good to eat. If they are bad, your nose will tell you! It’s still important however to discard any Mussels prior to cooking that aren’t closed and don’t close when gently tapped, as they’re not alive and it’s impossible to tell how long they’ve been dead for. And remember to remove Mussels from the pan as soon as they open so as not to overcook them.
