Smoked Haddock With Whole Grain Mustard Sauce & Poached Egg

The scent of smoked fish always transports me back to my childhood summers spent in the Scottish Highlands. My grandfather, a seasoned fisherman, would bring home his daily catch, and the aroma of smoked haddock wafting from the kitchen was a signal of a comforting and delicious meal to come. This dish, with its creamy mustard sauce and perfectly poached egg, is my refined take on those simple, heartwarming flavors.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 25 minutes
• Total Time: 35 minutes
• Servings: 4
• Dietary Type: Pescatarian

Ingredients

• 700g smoked haddock (or other smoked fish, e.g. cod, coley, etc.)
• 150ml double cream
• 1 tablespoon coarse grain mustard or 1 tablespoon Dijon mustard
• 1 tablespoon honey
• 4 eggs
• 3 large peeled potatoes
• 4 thinly sliced spring onions
• Salt
• Pepper

Equipment Needed

• Saucepan
• Small Saucepan
• Potato Masher
• Slotted Spoon
• Small Bowls (for poaching eggs)

Instructions

1. Begin by preparing the haddock. Cut the 700g smoked haddock into four equal-sized portions. This ensures even cooking and elegant presentation.

2. Place the haddock portions in a large saucepan. Add cold water until the fish is just covered. Avoid using too much water, as this can dilute the flavor.

3. Bring the water to a gentle simmer over low heat. Poach the haddock for about 4 minutes, or until it is cooked through. The fish should be opaque and flake easily with a fork. Be careful not to overcook, as this will make the fish dry and rubbery.

4. Carefully remove the haddock from the saucepan using a slotted spoon and set aside to keep warm. You can cover it loosely with foil to retain heat.

5. While the haddock is poaching, prepare the mashed potatoes. Place the 3 large peeled potatoes in a separate saucepan, cover with cold water, and bring to a boil. Reduce the heat and simmer until the potatoes are soft and easily pierced with a fork. This usually takes about 15-20 minutes.

6. Drain the potatoes well and return them to the saucepan. Mash them thoroughly using a potato masher until smooth.

7. Add the 4 thinly sliced spring onions to the mashed potatoes and mix well. The spring onions add a fresh, vibrant flavor that complements the smoked haddock.

8. Season the mashed potatoes with salt and pepper to taste. Be mindful of the salt content, as smoked haddock can already be quite salty.

9. Now, prepare the whole grain mustard sauce. In a small saucepan, heat the 150ml double cream over low heat.

10. Add the 1 tablespoon coarse grain mustard (or Dijon mustard) and 1 tablespoon honey to the cream.

11. Whisk gently to combine the ingredients until the sauce is smooth and well emulsified. Remove from the heat and set aside. Be careful not to boil the cream, as this can cause it to curdle.

12. Finally, poach the 4 eggs. There are several methods for poaching eggs, but a simple approach is to bring a saucepan of water to a gentle simmer (not a rolling boil). Add a splash of vinegar to the water, which helps the egg whites coagulate. Crack each egg into a small bowl before gently sliding it into the simmering water.

13. Poach the eggs for about 3-4 minutes, or until the whites are set but the yolks are still runny. Use a slotted spoon to carefully remove the poached eggs from the water and gently pat them dry with a paper towel.

14. To serve, place a generous spoonful of mashed potatoes in the center of each plate.

15. Gently place a portion of smoked haddock on top of the mashed potatoes.

16. Top each portion with a poached egg.

17. Drizzle the honey mustard sauce generously over the haddock and poached egg. Serve immediately and enjoy!

Expert Tips & Tricks

• For extra flavor, try adding a knob of butter and a splash of milk to the mashed potatoes for a richer, creamier texture.
• To prevent the poached eggs from spreading, create a whirlpool in the simmering water before adding the eggs. This helps them to form a neat shape.
• If you prefer a thicker sauce, you can simmer the honey mustard sauce for a few minutes longer to reduce it slightly.
• For a more intense smoky flavor, use hot-smoked haddock instead of cold-smoked haddock.
• To keep the poached eggs warm, place them in a bowl of warm water until ready to serve.

Serving & Storage Suggestions

Serve the Smoked Haddock with Whole Grain Mustard Sauce & Poached Egg immediately for the best flavor and texture. The runny yolk of the poached egg adds a delightful richness to the dish that is best enjoyed fresh.

Leftovers can be stored in the refrigerator for up to 24 hours, but the quality will diminish over time. Store the components (haddock, mashed potatoes, and sauce) separately to prevent them from becoming soggy. Reheat the haddock and mashed potatoes gently in the microwave or oven. Reheating the poached egg is not recommended, as it will likely overcook. It’s best to make a fresh poached egg if you are reheating leftovers.

This dish is not suitable for freezing, as the texture of the haddock, potatoes, and sauce will be compromised.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of mustard in the sauce?
A: Absolutely! While coarse grain mustard adds a lovely texture, Dijon mustard works just as well for a smoother sauce.

Q: How can I tell if the haddock is cooked through?
A: The haddock is cooked when it turns opaque and flakes easily with a fork. Avoid overcooking, as it can become dry.

Q: Can I make the mashed potatoes ahead of time?
A: Yes, you can make the mashed potatoes a few hours in advance. Keep them warm in a slow cooker or reheat them gently before serving.

Q: What’s the best way to keep the poached eggs warm?
A: Place the poached eggs in a bowl of warm water until you’re ready to serve them. This will prevent them from getting cold and rubbery.

Q: Can I use frozen haddock for this recipe?
