Step by step
Rinse the clams and clean the mussels of their beards. Put them all in a saucepan with no other ingredients. Cover and cook for 5 minutes.
Tips
When you choose mussels, take care to remove those that do not open when cooked, because this means the mollusc has died. Both for clams and for mussels, while cooking the shells must open.
Trivia
Clams are particularly delicious and healthy molluscs, but they are purifying animals: for this reason, they must be purchased fresh.
