Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 400°F (200°C). Put the smoked haddock in a wide pan with the milk and onion halves. Bring to a gentle simmer and poach for 5 to 6 minutes, until the fish is opaque and flakes at 145°F (63°C).
Lift out the haddock, flake it into large pieces and set aside. Strain the poaching milk into a jug and keep it. Finely chop the onion.
Melt 15g of the butter in a pan, add the chopped onion and cook gently for 5 minutes until soft. Set aside.
Melt another portion of the butter in a large pan and fry the sliced mushrooms over medium-high heat for 5 minutes until golden. Set aside.
Put the spinach in a pan with a splash of water and wilt it over medium heat for 1 to 2 minutes. Drain, squeeze out the excess water and chop roughly.
Melt the remaining butter in a clean pan, stir in the flour and cook for 1 minute. Gradually whisk in the reserved milk and simmer for 3 minutes until thickened.
Off the heat, stir in the crème fraîche and half the grated Gruyère. Gently fold in the flaked haddock, spinach, mushrooms and onion, then spoon into a pie dish and let cool for 10 minutes.
Roll out the puff pastry to fit over the dish, lay it on top and trim the edges. Brush with the beaten egg yolk and water, scatter over the remaining Gruyère and cut a small vent in the top.
Bake for 35 to 40 minutes until the pastry is deep golden and the filling is hot and bubbling in the centre. Rest for 5 minutes before serving.

Fit is the average pairing score against spinach, butter, haddock, milk, flour, mushroom, cheese. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
