The most common recipe is for mussels marinière: wine, shallots, parsley and butter. For a lighter version - the dish has an average of 600 calories - you can opt for plain mussels. The mussels are steamed and simply garnished with a little butter, celery and leeks. Afterwards, depending on taste and appetite, many variations are possible, such as mussels with cream, beer, curry, garlic or "parquées", a Brussels recipe in which the mollusks are served raw with a mustard sauce, vinegar and water.
One last important point: mussels and fries taste even better when eaten with the fingers. So much the worse for sticky hands, to honor the very convivial dimension of this dish, we must forget the usual rules of propriety. Speaking of tradition, don't hesitate to eat it during the Braderie de Lille where, every year, about 500 tons of mussels and 30 tons of fries are served during the weekend!
