Zeeland Mussels and Moules-Frites: The Story of Belgium’s National Ritual
Some dishes tell the story of a country better than any history book. In Belgium, this one comes to the table in a black pot, its lid still steaming, with a cone of fries and a jar of mayonnaise alongside. You lift the lid, the steam rises, and for three seconds nobody says a word. Moules-frites isn't a recipe. It's a ritual, and it begins a hundred kilometres from here, in the cold waters of the Eastern Scheldt.
Our five preparations
Chef Adrien Schurgers and his brigade serve five traditional preparations, as Belgian as they come. Every pot is cooked to order over a high flame, covered: the mussels open in a few minutes in their own seawater.
• Marinière — the benchmark. Celery, onion, a knob of butter, cracked pepper, nothing else. The broth left at the bottom is the real test of a mussel kitchen.
• White wine — a sharper register: the wine deglazes the cooking juices and produces a lively broth, for anyone who finds marinière too well-behaved.
• Garlic cream — the generous one. Cream, confit garlic and reduced cooking liquor make a sauce a chip dives into without hesitation.
• White wine & Garlic cream — The best of both worlds. The freshness of a white-wine deglaze, followed by the roundness of confit-garlic cream. A full, generous broth for sauce lovers.
• Tarragon cream — our autumn favourite. Tarragon brings an aniseed note that lightens the cream and lifts the mussel without ever masking it.
The ritual: use your first empty shell as tongs to pick out the next mussel. Save the broth for last. And any mussel still shut after cooking simply goes to one side.
Zeeland: the North Sea’s kitchen garden
In Yerseke, a small Zeeland harbour on the Oosterschelde, mussels aren't fished: they're farmed. The seed mussels are sown on plots of seabed leased from the state, the mosselpercelen, where they grow slowly for two to three years with the rhythm of the tides. This bottom culture, with no ropes or wooden stakes, produces a mussel with a thick shell and firm, plump flesh, shaped by the brackish water of the Scheldt.
Before they're sold, the mussels spend a few days in desanding basins, in clear running water, until they've flushed out all their sand. You never see this step on the plate, but it's what separates a gritty mussel from one you enjoy to the last bite.
The season traditionally opens in summer and runs through to spring. The old rule of only eating mussels in months with an "R" (September to April) hasn't meant much since refrigerated transport came along, but it still gets one thing right: autumn is when Zeeland mussels are at their fullest and most flavourful. September, October, November are their three great months.
How Brussels made the mussel its own
Brussels has no sea. It had something better: a canal. Dug in the 16th century to link the city to the Rupel and on to the Scheldt, the Willebroek Canal brought the port of Antwerp, and Zeeland beyond it, within reach by boat. Fish and shellfish travelled all the way into the heart of the capital, where the fish market grew up. The Quai aux Briques and the Sainte-Catherine district still bear its traces today.
Here the mussel was the people's shellfish: cheap, sold by the measure, cooked in the estaminets and at street stalls. Its pairing with fried potatoes took hold in the 19th century, when street frying became a full-fledged urban trade. Where the fry actually came from is still up for debate, with the Meuse valley and Paris both claiming it, but the pairing itself is unmistakably Belgian. It wasn't born in a chef's kitchen. It was born on the street, and only later made its way to the table.
The fries: the other half of the dish
No soggy fry has ever done a good mussel justice. Ours are cut fresh and fried twice.
• First fry, at a moderate temperature: the potato cooks through without colouring. It is then left to cool and firm up.
• Second fry, hotter, just before the plate leaves the pass: the crust forms — golden and brittle — while the inside stays soft.
Both baths are in beef tallow, as in the country’s best fritures. That is what gives the round, faintly nutty flavour no vegetable oil reproduces. Alongside comes our own mayonnaise, made in-house with mustard: thick enough for a chip to stand upright in it.
What to drink
A crisp, slightly tart witbier is still the most Brussels pairing for moules marinières. With garlic cream, a good dry tripel stands up to the sauce. With tarragon, a dry, lively white (Chablis, Muscadet, Sancerre) works wonders. Our wine list and our Belgian beer list are there to fine-tune the match: just ask your server, it's exactly the kind of question we love.
Moules-frites in Watermael-Boitsfort, since 1683
Au Repos des Chasseurs, "the Hunters' Rest", lives up to its name: this is where, on the edge of the Sonian Forest, hunters stopped to rest in the 17th century. Three and a half centuries later, the house still plays the same role. It's a brasserie where people stop after a walk in the woods, with a bike leaning against the terrace and the whole family gathered around the table.
It's a rare setting for south-east Brussels: 120 seats on a terrace facing the trees, free private parking right outside, a kitchen led by Chef Adrien Schurgers, and five private rooms for group meals and banquets. Autumn is the time for mussels, and for a Sunday lunch after a walk in the forest, few places can match it.
Frequently asked questions
From Zeeland in the Netherlands, mainly from plots in the Oosterschelde estuary. They are bottom-cultured mussels, purged before dispatch, known for their firm and meaty texture.
Five : Marinière, white wine, garlic cream, tarragon cream, and white wine with garlic cream. All are served with our fresh fries, double-fried in beef fat, and our homemade mayonnaise.
From September to April, peaking in autumn — that is when the Zeeland mussel is at its fullest.
