Ingredients
- 1 tbsp unsalted butter
- 1 medium onion
- 400g medium potatoes (about 2), peeled and cut into 1cm cubes
- 250g smoked haddock
- 250ml whole milk
- ½ small bunch of parsley or chives, finely chopped
Instructions

- Step 6: Season the soup to taste and sprinkle over the chopped parsley or chives before serving.
Tips & Variations

- Substitute parsley with dill for a slightly different herbal note.
Storage

- Yield: 4 servings 1x
Description

Ingredients
Soup Base
- 1 tbsp unsalted butter
- 1 medium onion, finely chopped
- 400g medium potatoes (about 2), peeled and cut into 1cm cubes
- 300ml water
Fish and Milk
- 250g smoked haddock
- 250ml whole milk
Garnish
- ½ small bunch of parsley or chives, finely chopped
Instructions
- Sauté onion: Melt the unsalted butter in a saucepan over medium heat. Add the finely chopped onion and fry for 5-8 minutes until the onion is translucent but not browned to develop sweetness and flavor.
- Cook potatoes: Add the 1cm cubed potatoes and 300ml water to the saucepan with the sautéed onion. Bring to a boil, then reduce heat slightly and simmer gently for 10-15 minutes, until the potatoes are tender.
- Poach smoked haddock: While the potatoes cook, place the smoked haddock in a separate pan and cover with the 250ml whole milk. Cook gently over low heat for about 5 minutes or until the haddock is just tender and opaque.
- Flake haddock: Remove the haddock from the milk using a slotted spoon, reserving the milk in the pan. Transfer the fish to a plate and let it cool slightly. Once cool enough to handle, flake the fish into large pieces, removing any bones carefully.
- Combine fish and soup: Add the reserved milk and flaked smoked haddock back into the pan with the cooked potatoes and onion. Cook together gently for another 5 minutes to marry the flavors and warm through.
- Season and garnish: Season the soup with salt and freshly ground black pepper to taste. Sprinkle the finely chopped parsley or chives over the top before serving to add a fresh herbal note and color.
Notes
- Use smoked haddock for authentic smoky flavor; fresh or unsmoked fish would change the character of the soup.
- Do not let the onion brown during sautéing to keep the broth clear and mild in flavor.
- Reserve the milk used to poach the fish as it adds a delicate smoky flavor to the soup base.
- Serve Cullen skink hot as a starter or light meal, ideally with crusty bread or oatcakes for dipping.
- For a gluten-free version, confirm all ingredients are gluten-free and serve with gluten-free bread.
