Cullen Skink

About This Recipe

Cullen Skink is the most beloved soup of the Moray Firth coast — a creamy, deeply smoky chowder of Finnan haddie (cold-smoked haddock), potato, leek, and milk, named after the fishing village of Cullen on Scotland's northeast coast. Skink originally meant a shin-of-beef broth in Old Scots, but by the 19th century it had come to mean any thick stewy soup. The technique is twofold: poach the smoked haddock gently in milk to infuse the broth with that signature smoky character, then build the soup around it with floury potatoes that partially dissolve. The result is hearty, smoky, and silky — the perfect Highland antidote to a damp North Sea afternoon. Served with thick brown bread and butter.

Ingredients

Serves 4

• 500 gundyed smoked haddock (Finnan haddie or natural-smoked)
• 500 mlwhole milk
• 1bay leaf
• 6black peppercorns
• 40 gunsalted butter
• 1 largeleek (white and pale green parts), finely sliced
• 1 smallyellow onion, finely diced
• 500 gfloury potatoes (Maris Piper or Russet), peeled and cubed
• 400 mlwater or light fish stock
• 100 mlheavy cream
• 1 small bunchflat-leaf parsley and chives, finely chopped
• freshly ground white pepper to taste
• brown bread and butter to serve

Instructions

1. 1

   Poach the haddock

   Place haddock skin-side down in a wide pan. Pour over milk; add bay leaf and peppercorns. Bring to a bare simmer over low heat (do not boil) for 6 minutes until the fish is just opaque and flakes easily.

2. 2

   Strain and flake

   Lift the fish onto a plate. Reserve the smoky milk through a fine sieve. Discard the bay and peppercorns. When cool enough, remove skin and bones from the haddock and flake the flesh into large chunks.

3. 3

   Sweat aromatics

   Melt butter in a heavy pot. Add leek and onion. Sweat over medium-low for 8 minutes until soft and translucent — no color.

4. 4

   Cook the potatoes

   Add cubed potatoes. Pour in the water (or fish stock) plus the strained smoked milk. Simmer for 18 minutes until the potatoes are very tender and starting to break apart at the edges.

5. 5

   Thicken naturally

   Crush about a third of the potatoes against the side of the pot with a wooden spoon — this thickens the broth into a silky cream without flour.

6. 6

   Add cream and fish

   Stir in the cream and gently fold in the flaked haddock. Warm through for 3 minutes — don't boil hard or the fish breaks up.

7. 7

   Season and serve

   Crack over white pepper. Ladle into deep warm bowls. Scatter generously with parsley and chives. Serve with thick slices of brown bread and good salted butter.

Variations

• •

  Add 100 g sweetcorn at the end for a Scottish-American chowder twist.

• •

  Substitute cream with crème fraîche for a slightly tangier finish.

• •

  Top with a soft-poached egg per bowl for a richer winter version.

Storage

Refrigerate up to 2 days. Reheat very gently — the fish overcooks easily. Do not freeze; the milk and potatoes both turn grainy.
