Choucroute de la Mer (Seafood Sauerkraut)
Why this recipe works
- Aromatic base: Shallot, juniper, peppercorns and bay gently perfume the sauerkraut before the seafood is added.
- Bright but balanced: Rinsing and squeezing the sauerkraut softens its sharpness, while lemon restores freshness at the end.
- Gentle one-pot cooking: The seafood steams directly over the sauerkraut, keeping the fish tender and letting the shellfish juices enrich the cabbage.

Authenticity notes
- Seafood variation: Choucroute de la Mer is a coastal-style variation of Alsatian choucroute, replacing the usual cured meats with fish and shellfish.
- Wine-simmered cabbage: Gently simmering sauerkraut with white wine and aromatics gives the dish its recognisable savoury-tangy base.
Ingredient notes
- Prepare the sauerkraut properly: Rinse and squeeze the sauerkraut well so it stays lively without making the finished dish too sharp or watery.
- Choose fresh mussels: Use mussels that smell clean and briny, and discard any that are cracked or do not close when tapped before cooking.
- Use a dry white wine: A dry white wine keeps the cabbage bright and savoury; a sweeter wine will make the dish rounder and less crisp.
Common mistakes
- Boiling too hard: Keep the sauerkraut at a gentle simmer once the wine is added; a rapid boil can make the cabbage harsh and the seafood tough.
- Overcooking the seafood: Add the fish, prawns and mussels only at the end, then cook just until the mussels open, the prawns turn pink and the fish flakes easily.
- Keeping leftovers too long: This dish is best eaten straight away. If storing leftovers, chill them quickly and reheat gently so the seafood does not become rubbery.
Timing notes
- Serve as soon as the seafood is cooked: The texture is at its best immediately after steaming, while the fish is still moist and the mussels are freshly opened.
- Best on the day it is made: Because the dish relies on delicate seafood, it is better served fresh rather than made fully in advance.

Ingredients
Instructions
- Thinly slice the shallots. Lightly crush the juniper berries and black peppercorns with the side of a knife to help them release their aroma. Cut the sea bass into large portions and set aside.
- Rinse the sauerkraut in a colander under cold water, then squeeze it well so it is damp rather than dripping. This keeps the flavour bright without becoming overly sharp. Set aside.
- Melt 40 g of the butter in a large pot over a medium heat. Add the shallots and cook for 3 to 4 minutes until softened but not coloured. Stir in the crushed juniper berries, peppercorns and bay leaves.
- Add the sauerkraut and pour in the white wine. Bring to a gentle simmer, then cover and cook over a low heat for 20 minutes so the cabbage perfumes the wine. Keep it at a quiet bubble, not a rapid boil.
- Meanwhile, scrub the mussels and pull off any beards; discard any that are cracked or do not close when tapped. If needed, rinse the prawns quickly and pat dry. Zest the lemon, then cut it into wedges.
- Nestle the sea bass on top of the sauerkraut, then scatter over the prawns and mussels. Cover and steam for 6 to 10 minutes, until the mussels have opened, the prawns are pink, and the fish flakes easily. Discard any mussels that remain closed.
- Turn off the heat and add the remaining 20 g butter, letting it melt into the sauerkraut for a glossy finish. Stir in the lemon zest, then taste the cabbage and adjust with a squeeze of lemon if you want it brighter. Serve hot with lemon wedges alongside.
Recipe notes
Tips
- Keep the heat low once the wine is added; a gentle simmer keeps the sauerkraut tender and stops the seafood from overcooking.
- For best results, choose mussels that smell clean and briny, and cook them the day you buy them.
- If serving anyone who is pregnant, elderly, or immunocompromised, make sure the seafood is thoroughly cooked and the mussels are fully opened before eating.
Substitutions
- Replace sea bass fillet with sea bream for a similar delicate texture and cooking time.
- Replace dry white wine with a slightly sweeter white wine if that is what you have; the dish will taste rounder and less sharp.
- Replace unsalted butter with salted butter, then go easy on any additional seasoning at the table.
Storage
- Refrigerate up to 1 days
- Best eaten straight away. If you have leftovers, cool quickly and refrigerate; reheat the sauerkraut gently in a covered pot until piping hot, then add the seafood just long enough to warm through to avoid it turning tough.
