-
Put the haddock skin side down in a wide pan with the milk and bay. Bring to a bare simmer and poach 5 minutes.
-
Lift the fish out onto a plate. Strain the milk and keep it. Peel off the skin and flake the flesh into large pieces, checking for bones.
-
Melt the butter in the pan and cook the onion and leek over low heat for 10 minutes without colouring.
-
Add the potatoes and the water, bring to a simmer and cook 15 minutes until soft.
-
Crush about a third of the potatoes against the side of the pan — that is the thickener.
-
Pour the reserved milk back in and warm through without boiling.
-
Add the cream, then the flaked haddock, and heat 2 minutes only.
-
Season with white pepper, and taste before adding any salt — the fish has usually done that job.
-
Serve with chives, parsley and oatcakes or bread.
Chef’s Tips
- Undyed haddock. The yellow stuff makes a soup that tastes of dye and salt.
- Poach the fish in the milk that becomes the soup. Nothing is wasted.
- Never boil once the milk is back in — it will split.
Common Substitutions & Variations
- Double cream won't whip if you swap it, but for the cooking itself, full-fat crème fraîche or a lower-fat single cream works in its place.
Pairing Suggestions
- Oatcakes or crusty bread
- A dry white wine
- A dram of Speyside whisky
Storage & Reheating
Refrigerate up to 2 days and reheat gently. Do not freeze — the potato goes grainy.
