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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body of the cakes and gives them their flavour.
- Potatoes
- Add bulk and softness, helping the cakes hold together while staying tender.
- Melted butter
- Adds richness and moisture to the mixture.
- Egg
- Binds the mixture so the cakes hold their shape.
- Breadcrumbs
- Form a crisp, golden browned coating when fried.
The step that matters
Fry in hot fat until golden brown. Fat that is hot enough sears the breadcrumb coating quickly, so it browns and crisps before the cakes absorb excess oil and turn greasy or fall apart.
