Clean and Debeard the Mussels
10 Mins • Hands On
Cold water, about 10°C (50°F)
Scrub each mussel under cold running water and tug the beard (the hairy tuft) toward the hinge until it comes away. Tap any open mussel on the bench — if it does not close, throw it away. Rinse in a second change of cold water and set aside in a colander.
Do this last, just before cooking, so the mussels never sit around wet and warm.
Done when: Mussels are clean, bearded, and all open ones that refused to close are discarded.

First Fry the Potatoes
12 Mins • Frying
160°C (320°F) oil
Heat the oil to 160°C (320°F). Fry the dried potato batons in small batches for 5–6 minutes until pale and soft but not coloured. Lift out, drain on paper, and leave to cool — this first fry cooks the inside.
Fry in batches. A crowded pan drops the oil temperature and the fries go limp.
Done when: Fries are pale gold, soft inside, and cool enough to handle.

Steam the Mussels
8 Mins • Stovetop
Rolling boil, about 100°C (212°F)
Melt the butter in a large pot over medium-high heat and soften the shallots, garlic and celery for 2 minutes. Pour in the wine, bring to a rolling boil, tip in the mussels, lid on, and shake the pot once or twice. Cook 5–6 minutes until every shell has opened, then stir in the cream and parsley.
Do not overcook — mussels turn rubbery in a minute. As soon as the shells open, they are done.
Done when: All shells are open and the meat is plump; any mussel that stayed shut goes in the bin.

Second Fry for Crispness
5 Mins • Frying
180°C (350°F) oil
While the mussels rest, heat the oil to 180°C (350°F) and fry the potatoes again in batches for 2–3 minutes until deep gold and crackling. Drain well, salt at once, and toss.
Salt fries the moment they leave the oil — salt sticks to hot fries and slides off cold ones.
Done when: Fries are deep gold, crisp outside, fluffy inside, and salted while hot.

Serve in the Pot
3 Mins • Plating
Serve hot, about 65°C (150°F)
Ladle the mussels and their broth into wide bowls or serve the pot at the table with an empty bowl for shells. Pile the fries alongside — never on top of the mussels, or they steam soft. Put mayonnaise on the table and eat with your fingers and a fork.
Serve the broth in the bowl with the mussels; it is half the dish. Crusty bread for dipping is never wrong.
Done when: Mussels steaming in their broth, fries crisp and golden on the side.

Eat the mussels straight from the pot with the fries on the side and the broth for dipping — that is how a Brussels brasserie serves it, and it needs nothing else.
