Top tips for cooking mussels

Mussels should be closed before you cook them. If they are open then they are dead. This is bad. Tap on the shell with your fingernail. If the mussel is alive it will close up. To clean the mussels put them in a bowl with cold water and some flour. This helps them to expel any sand and grit that's inside them. After cooking discard any mussels that have not opened up. It is always best to buy a few more mussels than what you need as you, inevitably, end up discarding a few.
