Ingredients

Soup Base

  • 1/2 onion, chopped
  • 6 carrots, peeled and cut into rough chunks
  • 3 parsnips, peeled and cut into rough chunks
  • 1 tbsp olive oil
  • 150g red lentils
  • 400ml boiling water (or vegetable stock)
  • Salt and pepper to taste

Fish & Garnish

  • 400g white fish (cod, pollock, haddock, or similar), boneless
  • 1 limequat or kumquat (or use zest and juice of 1/2 lime)
  • Fresh parsley, finely chopped

Instructions

  1. Prep vegetables: Peel and chop onion. Peel carrots and parsnips, and cut them into rough chunks.

  2. Sauté and simmer: Heat olive oil in a pot over medium heat. Add onion, carrots, and parsnips. Sauté for 5-6 minutes until slightly softened. Add red lentils and boiling water. Cover with lid and cook for 20 minutes until everything is tender.

  3. Prep garnish: Meanwhile, finely chop parsley and set aside. Cut limequat into very small cubes with peel and all, removing any seeds. (If using regular lime, zest it and juice half.)

  4. Check fish: Run your fingers over the fish fillets to feel for any bones. Remove them carefully if found, and pat fish dry.

  5. Blend soup: Blend the soup until smooth (or leave some texture if you prefer). Return to pot. Thin with a bit of water if too thick. Stir in chopped limequat (or lime zest and juice) and season generously with salt and pepper.

  6. Poach fish: Place fish fillets in the soup. Cover with lid and simmer gently for 5 minutes until fish is just cooked through and flakes easily.

  7. Serve: Ladle soup into bowls with fish portions. Top with fresh parsley.

Notes

  • Fish options: Any mild white fish works - cod, pollock, haddock, or tilapia.
  • Limequat substitute: If you can’t find limequats, use the zest and juice of half a lime instead. The citrus really brightens the soup!
  • Make ahead: Make the soup base ahead and add fish just before serving.
  • Storage: Soup base keeps 3-4 days. Store cooked fish separately.
  • Variations: Add a dollop of Greek yoghurt when serving, or swap fish for salmon.

Equipment Used
