Cullen Skink Recipe

Traditional Scottish Smoked Haddock Soup

History & Origins

Cullen Skink originates from the fishing village of Cullen on Scotland’s northeast coast. The name “skink” comes from a Scots word meaning “soup” or “shin of beef,” though this version uses fish. Traditionally made with locally caught smoked haddock, potatoes, and onions, it was a practical way to use available ingredients.

The soup gained popularity beyond Moray and is now considered one of Scotland’s signature dishes, featured in restaurants and home kitchens across the country.

Ingredients

For 4 servings:

• 1 lb (450g) undyed smoked haddock (Finnan haddie is traditional)
• 1 medium onion, finely chopped
• 1 large potato, diced into ½-inch cubes
• 1½ pints (850ml) whole milk
• 1 bay leaf
• Salt and freshly ground black pepper to taste
• 2 tablespoons butter (optional)
• Chopped fresh parsley for garnish

Method

Step 1: Prepare Haddock

Place the smoked haddock in a single layer in a large pan. Cover with water and bring to a gentle simmer. Cook for 5-7 minutes until the fish flakes easily.

Step 2: Remove Fish

Carefully remove the haddock with a slotted spoon, reserving the cooking liquid. Let the fish cool slightly, then remove skin and bones, flaking the flesh into large pieces.

Step 3: Cook Vegetables

Step 4: Add Liquids

Pour in the milk and about 1 cup of the reserved fish cooking liquid. Bring to a very gentle simmer; do not boil vigorously, as the milk may separate.

Step 5: Simmer Soup

Simmer for 15 to 20 minutes until potatoes are tender. Season with black pepper and a little salt (the haddock is already salty).

Step 6: Add Fish

Gently stir in the flaked haddock and heat through for 2-3 minutes. Remove the bay leaf.

Step 7: Serve

Ladle into warm bowls, garnish with chopped parsley, and serve with crusty bread or oatcakes.

Cooking Tips

Choosing Haddock

Undyed smoked haddock (natural colour) is traditional and preferred. Dyed haddock (yellow) works but alters flavour and appearance.

Potato Choice

Use floury potatoes like Maris Piper or King Edward that break down slightly to thicken the soup.

Milk Temperature

Heat milk gently to prevent curdling. Never boil rapidly.

Fish Preparation

Poaching the haddock first removes excess salt and ensures tender flakes.

Traditional Variations

Cullen Style

The original uses only haddock, potatoes, onions and milk: no cream or thickeners.

Restaurant Style

Some chefs add a splash of cream at the end for extra richness.

Modern Twist

A little smoked paprika can enhance the smoky flavour without overpowering the haddock.

Serving Suggestions

Traditional Accompaniments

Serve with:

• Scottish oatcakes
• Crusty bread
• Buttered soda bread

Wine Pairing

A crisp white wine like Chardonnay or a light lager complements the smoky flavours.

As a Main Course

Serve in larger portions with added vegetables for a complete meal.

Common Mistakes

• Overcooking the fish: becomes tough
• Boiling the milk: causes separation
• Using dyed haddock: alters authentic flavour
• Adding too much salt: haddock is already salty
• Skipping potato cooking: potatoes must be tender

Storage & Reheating

Cullen Skink stores well for 2-3 days in the refrigerator. Reheat gently on the stove; microwaving may cause milk separation. The soup thickens when chilled; add a little milk when reheating.
