  • Third Step: Croûtons
  • 125 ml (1/2 cup) clarified butter
  • 8 thick slices sourdough
  • 1 garlic clove


  1. For the soup: cut the vegetables in a mirepoix dice.
  2. Heat the olive oil, then add the vegetables, a pinch of salt and sauté until the evaporation of their water and then deglaze with white wine, reduce to dryness and add thyme, peeled garlic and bay leaf.
  3. Wet ⅔ of the mass with water.
  4. Leave to cook on very low heat for 2 hours then mix all while removing thyme and bay leaves.
  5. Adjust seasoning.
  6. Put the shrimp stock in a saucepan and heat to just below a simmer. Reserve.
  7. Heat a seperate soup pot or dutch oven over medium heat and add the salt pork. Cook for 1-2 minutes to heat the fat.
  8. Add the onions, sprinkle with ½ teaspoon salt, turn heat to medium low, and cook for 5 minutes (no browning on the onions).
  9. Tie the herbs and bay leaf in a cheesecloth and add to the pot along with the potatoes and the warm fish stock.
  10. Taste the soup at this point, adjust seasoning with salt. Be careful not to over season, since the soup liquid will reduce.
  11. Increase the heat and bring the soup to a boil. Then reduce the heat to low and simmer the soup until the potatoes are tender, about 30-40 minutes.
  12. At this point, there should be enough broth to poach the fish in, add an extra cup of stock (preferred) or water to the soup if it is too thick.
  13. Taste the soup and re-check the seasoning. Remove the cheesecloth with herbs and bay leaf.
  14. Add one third of the fish fillets to the barely simmering soup, and poach until opaque. Remove with a slotted spoon and keep warm.
  15. Repeat twice, with the remaining fish and shellfish. (Note: Make sure all the fish you add is immersed in the broth, but near the surface so you can scoop it out when cooked. Be careful when handling the fish, so it doesn’t fall apart. You may need to gently turn the fillets. Add less fish at a time if it doesn’t all fit.)
  16. Meanwhile, for croûtons, heat clarified butter in a frying pan over medium heat, add bread and cook, turning once, until golden (1-2 minutes each side). Rub bread and serving bowls with garlic clove, then discard garlic.
  17. Divide croûtons among bowls, top with potatoes, onions and shellfish, then ladle over fish and soup. Season liberally with freshly ground black pepper and serve hot. Sprinkle lightly with minced chervil or parsley.
