Clementine–Vermouth Mussels, or: The Ocean on a California Weekend
I grew up thinking mussels belonged to cold evenings—foggy Paris sidewalks, a crowded bistro, the kind of steam that perfumes your scarf for hours. Then I moved to California and realized winter here still tastes like citrus. That’s how these Clementine–Vermouth Steamed Mussels happened: classic moules marinière technique (shallots, gentle steam, lid on, no drama), but with a West Coast grin.
The inspiration was equal parts fishmonger and farmers’ market. One January, my mussel guy handed me a bag that smelled like clean tidepools, and two stalls later someone pressed a clementine into my palm like it was sunshine you could peel. I went home, poured dry vermouth (because it’s bright and slightly herbal without shouting), and whisked in butter with herbs and a little nori—my favorite “don’t tell anyone” ingredient when I want briny depth without heaviness.
What makes it special to me is the finishing contrast: avocado-celery crunch—creamy, crisp, chilled—against that glossy, oceanic broth.
Make it yours: swap tarragon for dill, add chile flakes, or finish with preserved lemon. Just promise me grilled sourdough for dunking. I’m French, not a monster.

Clementine–Vermouth Steamed Mussels with Nori–Herb Butter + Avocado-Celery Crunch
This is my winter-gathering mussel moment: classic moules marinière technique (gentle steam, lid on, no drama), then a glossy herb butter that tastes like the ocean took a vacation in California. Clementine and dry vermouth keep it bright, nori sneaks in that briny bass note, and a little avocado-celery crunch turns the whole bowl into a bistro starter that feels sunlit instead of heavy. Serve with grilled sourdough for dunking—because I’m French, not a monster.

Instructions
- 1
Make the avocado-celery crunch: In a bowl, toss 1 avocado, diced small, 1 celery stalk, diced small, 1/2 cup cucumber, diced small, 1 pinch kosher salt, 1 tsp clementine zest, 1 tbsp clementine juice, and 1 tbsp extra-virgin olive oil. Pepper it generously. Set aside while you cook the mussels (5–10 minutes is perfect).

Tip: Keep the dice small so it reads like a bright little ‘condiment salad’ that can land on top of hot mussels without feeling clunky.

Build your steaming base: In a wide pot with a lid over medium heat, warm 1 tbsp olive oil and 1 tbsp unsalted butter. Add 1 shallot, finely sliced and cook until soft and translucent, about 3–4 minutes. Add 2 cloves garlic, thinly sliced and cook 30 seconds—just until it smells like you’re doing something very correct.
5 min
Tip: Wide pot = faster, gentler steaming (mussels want a sauna, not a wrestling match).
- 3
Gentle steam, moules marinière style: Add 1/2 cup dry vermouth, 4 sprigs fresh thyme, 1 bay leaf, 1/2 tsp black pepper, and the remaining 1 tsp clementine juice (save the zest for the topping already). Bring to a lively simmer. Tip in the 2 lb fresh mussels, scrubbed and debearded, cover, and steam 4–6 minutes, shaking the pot once or twice, until most mussels open.
6 min
Tip: The moment they open, they’re done. Overcooked mussels taste like regret—pull the pot off the heat as soon as they’re open.

Finish with nori–herb butter: Off heat, discard thyme sprigs and bay leaf. Add the remaining 3 tbsp unsalted butter, 1/3 cup flat-leaf parsley, finely chopped, 2 tbsp chives, finely sliced, and 1 nori sheet, crumbled. Gently swirl the pot until the butter melts into a glossy, briny-citrus broth that clings to the shells.
2 min
Tip: This is my lazy-person’s beurre monté moment—swirl, don’t boil. If the broth seems too hot, let it sit 30 seconds before you add the butter.
- 5
Serve like a bistro with California sun: Spoon mussels and broth into warm bowls. Crown each with a small handful of the avocado-celery crunch. Serve immediately with 1 loaf grilled sourdough or baguette for dunking.
3 min
Tip: If you want to be extra, toast the bread hard so it acts like a raft, not a sponge that gives up mid-dunk.
Chef's Notes
This dish is basically how I want February to taste: coastal, bright, a little feral in a good way. The nori is my California cheat code—like adding a whisper of tidepool without reaching for anything fussy. Wine-wise: I pour something saline and nervy (a Muscadet-style white, a crisp coastal Chardonnay with restraint, or a pét-nat that behaves—mostly).

French soul, California sun
I grew up in a small village outside Lyon, where my grandmother taught me that the best meals come from respecting your ingredients. After training at Le Cordon Bleu and spending years in Parisian kitchens, I moved to San Francisco and fell in love with California's farmers markets and wine country. Now I cook the food I wish my grandmother could taste—French technique with California abundance, where a perfect roast chicken might come with Meyer lemon and wild fennel instead of tarragon.
