Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish Pudding
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.
Prepare the fish
Remove all skin and bones from the fish, then break it into small pieces.
Mash the fish with butter and mashed potatoes until smooth.
Season the mixture with pepper and salt to taste.
Shape and bake
Place the mixture in a shallow dish, creating a border around the edge.
Smooth the top with a broad knife dipped in hot water and score it across.
Bake in a 400°F (200°C) oven until light brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Provides the main body and flaky texture of the pudding.
- Butter
- Adds richness and moisture, helping the mixture stay soft and smooth.
- Mashed potatoes
- Binds the fish and adds body so the mixture holds together when baked.
The step that matters
Smoothing the top and scoring it. Smoothing with a knife dipped in hot water gives an even, glossy surface that browns uniformly. Scoring lets steam escape so the top does not crack or puff unevenly in the oven.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, pepper):
- Capsicumfits about as well
- Potatothe original
- Tomatofits less well
- Asparagusfits less well
Fit is the average pairing score against fish, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
