Trim, scrape, and thoroughly wash the mussels.
Peel the onion and celery, then chop into pieces. In a large pot, melt a bit of butter and sauté the onion and celery for 4-5 minutes until softened. Add the mussels, pour in the white wine and a pinch of pepper, cover, and bring to a boil. Cook, stirring occasionally, until the mussels open.
Once opened, drain the mussels, shell them, and strain the cooking liquid through a fine sieve. Return the liquid to the pot and reduce by half. Set aside.
Slice the leek whites and gently steam them in a little butter for about 10 minutes until tender.
Meanwhile, in a sauté pan, sweat the chopped shallots and thyme in butter, then deglaze with Fine de Languedoc. Reduce by three-quarters. Add the shelled mussels, steamed leeks, cream, and reduced mussel broth. Simmer for 5 minutes, then serve in ramekins.
Expert Tip: Opt for bouchot mussels for superior flavor, though they're smaller and best outside May-October. Bouzigues mussels offer a larger, more bountiful alternative.
Joëlle's Insight: Mussel prep is the main task—save time by buying pre-scraped mussels from the market for a small premium.
Suggested wine: Château Carbonnieux adds a unique flair, or pair with a solid white Graves.
