Mussels marinière — Belgium

Mussels marinière, also called mussels à la marinière, are a preparation of mussels cooked in a broth built from butter, shallots, white wine and parsley. The dish is closely tied to a side of crisp fries, together forming what is called mussels-and-fries. It is reported from Belgium and from the north of France, a stretch of coast and border country where the combination of mussels and fries is treated as a shared dish rather than one belonging to a single country; on AllGastronomy the Belgian and French versions are each recorded on their own page, with neither set above the other. Shallots are softened in butter, then a splash of white wine is added and brought to a bubble before the cleaned, debearded mussels go in. The pot is covered and shaken over high heat for only a few minutes, just long enough for the shells to open and release their liquid into the broth, which is finished with a scatter of chopped parsley. The dish is served straight from its cooking pot, mussels and broth together, with a bowl for the empty shells and a mound of fries on the side; the exact ratio of butter to wine, and whether cream is added at the end, differs from one kitchen to the next across Belgium.
