Why it works: Haddock and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 200 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Haddock Pie
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Remove skin and bones from the haddock and cut it into neat pieces.
Place the fish in a pudding dish.
Sprinkle with pepper, salt, and lemon juice.
Pour the thick white sauce over the fish.
Top and bake
Mix the mashed potatoes with milk and butter.
Spread them neatly over the fish, then smooth the potatoes.
Mark with a fork.
Add bits of butter on top.
Bake in a 400°F (200°C) oven for about 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the pie and cooks through in the oven.
- Mashed potatoes
- Form a soft topping that bakes into a golden, sturdy crust over the fish.
- Thick white sauce
- Adds moisture and richness so the fish stays tender while baking.
- Butter
- Adds fat that helps the potato topping brown and gives a richer flavour.
The step that matters
Spreading and smoothing the potato topping. The potato layer must cover the fish fully and be smoothed evenly so the fish stays moist and the topping browns evenly rather than in patches.
