Ingredients
- Butter for the pan
- 2½ cups whole milk
- ½ large white onion
- 4 cloves
- 1 bay leaf
- 1¾ pounds white fish, like halibut or cod
- 3 ounces smoked salmon strips, skins cut off, or 3 ounces smoked salmon, skin removed
- 1 cup frozen peas
- 2 egg yolks
- 2 tablespoons cornstarch
- 3 ounces sharp English Cheddar, grated
- ⅓ cup chopped parsley
- 2 teaspoons white wine or vermouth
- Pinch of nutmeg
- Salt and pepper to taste
- 1 8-ounce sheet store-bought puff pastry, thawed
- 1 tablespoon of milk to glaze
Preparation
Preheat the oven to 400° F. In a 4- to 6-quart pot, place the milk, the onion studded with the cloves, the bay leaf, white fish, and smoked salmon. Bring the milk to a bubble, turn it down to a simmer, and allow the fish to poach for 5 minutes. Remove from the heat.
Using a slotted spoon, scoop out the fish and the other solids. Discard the onion and bay leaf. Crumble the fish and arrange it inside a buttered 9-inch pie pan. Sprinkle the frozen peas on top. Set aside. Whisk the yolks and cornstarch in a small bowl. Whisking constantly, ladle some of the warm milk into the egg mixture. Then scrape that mixture back into the pan full of poaching liquid and return to medium heat.
Add wine or vermouth, allow mixture to boil gently for 2 minutes, stirring constantly. The sauce should thicken to a warm pudding texture. Add cheese, parsley, and nutmeg. Stir until cheese is melted, remove from the heat, taste, adjust salt and pepper. Pour over the fish in the pie pan. Roll out the puff pastry sheet so that it is at least an inch larger than the pan on all sides. Carefully place it on top of the pie, tuck it under the lip of the pan, press the edges with a fork, and trim excess. Prick the top a few times to let out the steam. Brush it with milk. Place the pie on a sheet pan to catch any overflow, and slide into the oven for 25 to 30 minutes, until it’s golden and puffed. Serve right away.
