Why it works: Butter and potato are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Stewed Haddock
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Poach the fish
Place the haddock in a pan of salted water and simmer for 1 hour.
Remove the head and lay the fish on a platter.
Dress and bake
Pour drawn butter over the fish.
Spread enough mashed potatoes to cover the fish nicely.
Spread the whites of 4 eggs over the potatoes.
Bake in a 400°F (200°C) oven until light brown.

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 dish and flakes into tender pieces when simmered.
- Butter
- Adds richness and moisture to the fish as it is poured over.
- Mashed potatoes
- Forms a soft layer over the fish that helps keep it moist under the topping.
- Egg whites
- Set in the oven to form a light, lightly browned topping.
The step that matters
Bake until light brown. Egg whites set and brown in the oven, so taking the dish out too early leaves the topping soft and pale, while baking too long can dry it out.
Swap the potato
How well each one fits the dish's main ingredients (haddock, butter, egg):
- Potatothe original
- Chivefits about as well
- Asparagusfits less well
- Spinachfits less well
Fit is the average pairing score against haddock, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
