Step-by-Step Instructions

Step 1: Prepare Your Base

1. Melt butter in a heavy-bottomed pot over medium heat until foaming.
2. Add diced onion, stirring for 5–7 minutes until translucent and sweet-scented.
3. Sprinkle in flour to form a light roux; cook 2 minutes to eliminate raw flour taste.
   Tip: Swirl the pot in a gentle figure-eight to avoid scorching your roux.

Step 2: Build the Broth

1. Gradually whisk in your fish or vegetable stock, ensuring no lumps remain.
2. Pour in milk, stirring constantly until the mixture is smooth and slightly thickened.
3. Season lightly with salt and white pepper.
   Tip: If your soup separates, whisk in a splash of cold water off-heat to bring it back together.

Step 3: Simmer Potatoes & Haddock

1. Add peeled, diced potatoes; bring the liquid to a gentle simmer. Cover and cook 15–20 minutes until potatoes are just fork-tender.
2. Gently nestle smoked haddock fillets into the simmering broth. Cover and poach for 6–8 minutes until fish flakes easily.
   Tip: Poaching at a low temperature (around 80 °C/176 °F) preserves the haddock’s delicate texture.

Step 4: Flake & Finish

1. Remove fish with a slotted spoon and set aside.
2. Use a potato masher to lightly break up some potatoes, creating body and cloud-like thickness.
3. Flake the haddock into bite-sized pieces, discarding any skin or bones, and return to the pot.
4. Stir in chopped parsley, adjust seasoning, and remove from heat.
   Tip: For an extra velvety texture, blitz 10% of the soup in a blender and stir back in.

Step 5: Personalize & Serve

1. Ladle the Cullen Skink into warmed bowls.
2. Garnish with a drizzle of olive oil, extra parsley, and freshly ground black pepper.
   Tip: Pair with buttery soda bread or a crisp green salad to balance the richness.

Serving Suggestions

Common Mistakes to Avoid

1. Overcooking the haddock – leads to stringy texture. Poach gently and remove as soon as it flakes.
2. Skipping the roux – results in a thin, watery broth. Toast flour lightly to achieve luscious creaminess.
3. Using red potatoes – their waxy texture holds shape but lacks the starchy body of Yukon Golds.
4. High-heat simmer – can cause milk to curdle. Maintain a gentle bubble for smooth soup.
5. Underseasoning – smoked fish and potatoes absorb salt; taste mid-cook and adjust gradually.

Storing Tips for the Recipe

• Refrigerator: Cool completely, transfer to an airtight container, and store for up to 3 days.
• Freezer: Freeze in portioned, freezer-safe bags for up to 2 months; thaw overnight in the fridge.
• Reheating: Gently warm on low heat, stirring occasionally; add a dash of milk or stock if too thick.
• Prep-Ahead: Chop potatoes and onions a day before; store submerged in water to prevent browning.
• Meal-Prep Hack: Double the recipe and freeze single-serve portions for grab-and-go lunches.
