Instructions

1. Pat the sea bass fillets very dry with paper towels and season both sides with 4 g salt and 1 g black pepper. Keep chilled while you prepare the rest.
- 2
2. Place the parsnips in a saucepan with 240 ml fish stock, the cream, 2 garlic cloves, half of the thyme, and a pinch of salt. Bring to a gentle boil, partially cover, and cook over medium-low heat for 15 to 18 minutes, until very tender.

3. Meanwhile, heat 15 ml olive oil and 15 g butter in a wide pot over medium heat. Add the shallot and cook for 2 to 3 minutes. Stir in half of the remaining chopped garlic and cook for 30 seconds.

4. Add the mussels, red vermouth, 120 ml fish stock, and a little black pepper. Cover the pot and cook for 4 to 6 minutes, shaking once, until the mussels open. Remove from the heat, discard any that stay closed, and add half of the parsley. Keep warm.

5. In a large skillet, heat 15 ml olive oil over medium heat. Add the chard stems and cook for 2 minutes. Add the leaves, the remaining garlic, a pinch of salt, and 15 ml lemon juice. Sauté for 3 to 4 minutes, until the chard is tender but still bright. Keep warm.

6. Blend the cooked parsnips with their cooking liquid, the zest of half the lemon, and 15 g butter until smooth and creamy. If needed, add 1 to 2 more tablespoons of stock to adjust the texture. Taste and adjust salt and pepper.

7. Heat a nonstick or cast-iron skillet over medium-high heat for 2 minutes. Add the remaining olive oil. Place the sea bass skin-side down and press gently with a spatula for 20 seconds to prevent curling. Cook for 4 to 5 minutes until the skin is golden and crisp.
- 8
8. Flip the fillets and cook for 1 to 2 minutes more, depending on thickness, until the fish is juicy and just cooked through in the center. If you prefer to finish it in the oven, transfer it to a preheated oven at 200 °C / 400 °F for 2 minutes.

9. To serve, spread a layer of parsnip cream on each plate. Top with the sautéed chard, then place a sea bass fillet on top. Spoon the mussels around it with some of the red vermouth broth. Finish with the remaining parsley, a few extra thyme leaves, and drops of the remaining lemon juice.

10. Serve immediately while hot, so the sea bass skin stays crisp and the vermouth aroma in the mussels remains vivid.
Chef tips
Dry the sea bass skin thoroughly for the crispiest finish. Do not stir the mussels too much while they open so they stay plump. The parsnip cream should be silky and light; loosen it with warm stock, not water, to avoid diluting the flavor.
Substitutions
You can substitute sea bass with gilthead bream or branzino. Parsnips can be replaced with celeriac, keeping in mind that this would add the celery allergen. If you do not have red vermouth, use dry white wine with 1 teaspoon of honey or brown sugar to mimic its rounded flavor.
