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 ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Provides the main flavour and the flaky body of the fish balls.
- Potatoes
- Supply starch and bulk that bind the mixture and keep the balls soft inside.
- Egg
- Binds the mashed potato and fish so the balls hold their shape.
- Flour
- Forms a dry coating that helps the outside brown when fried.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Fry the balls in hot fat until golden brown. If the fat is not hot enough, the balls absorb oil and turn greasy, while the flour coating browns slowly. Hot fat sets the coating quickly and keeps the inside tender.
