Step by step

Remove all the mollusc meat from the shells one by one and transfer to the frying pan. Keep some shells aside as a garnish. Add the cooking juices from the pan, strained.

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.
