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
- Salt codfish
- Provides the main savoury flavour and salty seasoning of the cakes.
- Potatoes
- Supply starch and bulk that bind the mixture and give a soft, fluffy interior.
- Eggs
- Bind the mashed mixture together so the cakes hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Drop spoonfuls into the hot fat and fry until brown. If the fat is not hot enough, the cakes absorb grease and turn heavy instead of forming a crisp, browned crust. Frying in properly heated fat seals the surface quickly.
Swap the potato
