A vibrant green split pea and leek soup finished with butter and served with croûtons and crème fraîche.

Ingredients

  • 400g sea bass fillets
  • 300g baguette
  • 2 tbsp sliced leeks
  • 1/2 tsp cracked black peppercorns
  • 2 tbsp unsalted butter
  • 2 shallots, chopped
  • a handful of fresh chervil, chopped
  • lemon zest, to taste
  • 400ml dry white wine
  • 1 1/2 tsp bay leaves
  • 200g leeks

Instructions

  1. 1

    Heat extra-virgin olive oil in a large pot over medium heat and cook the minced garlic and sliced leeks gently until soft and fragrant.

  2. 2

    Stir in the cracked black peppercorns and bay leaves, toasting briefly until the kitchen fills with their aroma.

  3. 3

    Add the fresh mussels and carrots, stirring well to coat everything in the spiced base.

  4. 4

    Pour in the chicken stock, scraping up any browned bits from the bottom of the pot, and bring to a boil.

  5. 5

    Reduce the heat, cover, and let everything simmer gently until the fresh mussels is tender, about 40 mins.

  6. 6

    Stir in the puff pastry and continue simmering for a few minutes more, until heated through.

  7. 7

    Finish with the lemon zest and adjust the seasoning to taste.

Tips

Taste and adjust the seasoning right at the end — the chicken stock reduces as it simmers, concentrating the flavor.

Skim off any foam that rises during the first few minutes of simmering for a clearer, cleaner broth.
