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 ↓
To Dress Haddocks
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Clean and season the haddocks.
Place them neatly on a flat dish with a border of mashed potatoes.
Glaze the fish with the egg and place bits of butter on top and inside each fish.
Garnish with potato balls.
Bake and serve
Bake for 30 minutes at 350°F (175°C).
Pour a little melted butter and catsup over the dish before serving.

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 cooks through in the oven.
- Egg
- Glazes the fish, helping the surface brown and set in the oven.
- Butter
- Adds richness and moisture as it melts over and into the fish.
- Mashed potatoes
- Form a border around the fish and add a soft, starchy base for the dish.
The step that matters
Glaze the fish with the egg. The beaten egg coats the surface so it sets and browns during baking. Applying it evenly keeps the color uniform and helps hold the butter in place.
Swap the potato
How well each one fits the dish's main ingredients (haddock, egg, butter):
- Potatothe original
- Chivefits about as well
- Asparagusfits less well
- Spinachfits less well
Fit is the average pairing score against haddock, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
