## Step-by-Step Instructions

Now, let’s get cooking! Follow these detailed instructions to create your own delicious British Fish Pie.

**Part 1: Preparing the Fish Filling**

1. **Prepare the Fish:** Gently pat the white fish, smoked haddock, and prawns dry with paper towels. This will help them brown better in the next step.
2. **Sauté the Aromatics:** In a large saucepan or Dutch oven, melt the butter over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
3. **Make the Roux:** Sprinkle the flour over the softened onions and garlic. Cook for 1-2 minutes, stirring constantly, to create a roux. This will help thicken the sauce.
4. **Gradually Add the Liquids:** Gradually whisk in the milk, a little at a time, ensuring there are no lumps. Continue whisking until the mixture is smooth. Then, whisk in the fish stock (or vegetable stock).
5. **Simmer the Sauce:** Bring the sauce to a gentle simmer over medium-low heat. Add the bay leaf (if using) and cook for 5-7 minutes, stirring occasionally, until the sauce has thickened slightly. Remove the bay leaf before continuing.
6. **Add the Fish and Seafood:** Gently stir in the white fish, smoked haddock, and prawns. Be careful not to break the fish up too much. If using cooked mussels or clams, add them now as well. If using frozen peas or sweetcorn, add them now.
7. **Cook the Fish:** Reduce the heat to low, cover the saucepan, and simmer gently for 5-7 minutes, or until the fish is cooked through and flakes easily with a fork, and the prawns are pink and opaque. Be careful not to overcook the fish, as it will become dry.
8. **Stir in the Finishing Touches:** Remove the saucepan from the heat. Stir in the double cream, chopped parsley, chopped dill, lemon zest, and lemon juice. Season with salt, freshly ground black pepper, and a pinch of nutmeg to taste. Taste and adjust the seasoning as needed. Remember that smoked haddock can be quite salty, so be careful not to over-salt.
9. **Assemble the Filling:** Pour the fish filling into an oven-safe dish (approximately 25x30cm or 9×12 inches). Spread the filling evenly.

**Part 2: Preparing the Mashed Potato Topping**

1. **Boil the Potatoes:** Place the peeled and quartered potatoes in a large saucepan. Cover with cold water and add a pinch of salt. Bring to a boil over high heat, then reduce the heat to medium and simmer for 15-20 minutes, or until the potatoes are tender and easily pierced with a fork.
2. **Drain the Potatoes:** Drain the potatoes thoroughly in a colander. Return them to the saucepan.
3. **Mash the Potatoes:** Mash the potatoes using a potato masher or ricer until smooth. A ricer will produce the smoothest, fluffiest mashed potatoes. Be careful not to over-mash the potatoes, as this can make them gluey.
4. **Add the Butter and Milk:** While the potatoes are still hot, add the butter and milk. Mix until smooth and creamy. If you want to add grated cheddar cheese, mix it in now.
5. **Season the Mashed Potatoes:** Season the mashed potatoes with salt and freshly ground white pepper to taste. Taste and adjust the seasoning as needed.

**Part 3: Assembling and Baking the Fish Pie**

1. **Top with Mashed Potatoes:** Spoon the mashed potato topping over the fish filling, spreading it evenly to cover the entire surface. You can create decorative swirls or patterns on the surface using a fork.
2. **Bake the Fish Pie:** Preheat the oven to 200°C (400°F/Gas Mark 6). Place the fish pie in the preheated oven and bake for 20-25 minutes, or until the mashed potato topping is golden brown and slightly crispy. If the topping is browning too quickly, you can loosely cover the dish with aluminum foil.
3. **Rest Before Serving:** Remove the fish pie from the oven and let it rest for 5-10 minutes before serving. This will allow the filling to settle slightly and make it easier to serve.

## Tips for Success

* **Use the freshest ingredients possible:** The quality of your ingredients will directly impact the flavor of your fish pie. Choose fresh, high-quality fish and seafood.
* **Don’t overcook the fish:** Overcooked fish will be dry and rubbery. Cook the fish until it is just cooked through and flakes easily with a fork.
* **Season generously:** Seasoning is key to a flavorful fish pie. Don’t be afraid to season both the fish filling and the mashed potato topping generously.
* **Make it ahead:** The fish filling and mashed potato topping can be made ahead of time and stored separately in the refrigerator for up to 2 days. Assemble and bake the fish pie just before serving.
* **Add a cheesy twist:** Stir grated cheddar cheese into the mashed potato topping for an extra layer of flavor. You can also sprinkle grated cheese over the top of the mashed potatoes before baking.
* **Get creative with the topping:** Instead of plain mashed potatoes, try using sweet potato mash, celeriac mash, or a combination of potatoes and other vegetables. You can also top the pie with breadcrumbs or cheese for a crispy topping.
* **Use different types of fish and seafood:** Experiment with different types of fish and seafood to create your own unique fish pie. Monkfish, salmon, scallops, and mussels are all great additions.
* **Add vegetables:** Add vegetables such as peas, sweetcorn, carrots, or celery to the fish filling for extra flavor and nutrients.
* **Serve with a side salad:** A simple green salad or steamed vegetables make a perfect accompaniment to fish pie.

## Variations and Adaptations

This recipe is a great starting point, but feel free to experiment and adapt it to your own preferences. Here are a few ideas:

* **Smoked Fish Pie:** Use more smoked fish, such as smoked haddock or smoked salmon, for a smokier flavor.
* **Luxury Fish Pie:** Add expensive ingredients such as lobster, crab, or scallops for a truly decadent dish.
* **Vegetarian Fish Pie:** Use vegetarian fish substitutes such as marinated tofu or jackfruit, along with a variety of vegetables, for a vegetarian version.
* **Mini Fish Pies:** Make individual fish pies in ramekins for a fun and elegant presentation.
* **Spicy Fish Pie:** Add a pinch of chili flakes or a dash of hot sauce to the fish filling for a spicy kick.
* **Crust Topping:** For a different texture and appearance, consider using a puff pastry crust instead of mashed potatoes. Brush the pastry with egg wash for a golden-brown finish.

## Serving Suggestions

British Fish Pie is a hearty and satisfying meal on its own, but it’s even better when served with the right accompaniments. Here are a few serving suggestions:

* **Green Salad:** A simple green salad with a light vinaigrette provides a refreshing contrast to the richness of the fish pie.
* **Steamed Vegetables:** Steamed green beans, broccoli, or asparagus are healthy and delicious side dishes.
* **Crusty Bread:** Serve with crusty bread for soaking up the creamy sauce.
* **Pickled Onions or Gherkins:** The acidity of pickled onions or gherkins cuts through the richness of the pie.
* **Chutney:** A dollop of chutney, such as mango chutney or apple chutney, adds a sweet and savory note.

## Storing and Reheating Leftovers

Leftover fish pie can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, preheat the oven to 180°C (350°F/Gas Mark 4) and bake for 15-20 minutes, or until heated through. You can also reheat it in the microwave, but the mashed potato topping may not be as crispy.
