Why it works: Pepper and potato 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 ↓
Codfish Balls
Ingredients
Directions
Prepare
Wash, pare and cut the potatoes into quarters; let stand in cold water.
Wash the fish and pick into half-inch pieces; remove the bones.
Make the mixture
Put the potatoes and fish into a kettle, cover with boiling water and cook until potatoes are soft, about twenty-five minutes.
Drain off all the water.
Mash and beat until very light.
Add the butter and pepper, and when slightly cooled add the egg and more salt if needed.
Shape in a tablespoon.
Fry and serve
The fat should be hot enough to brown a piece of raw potato in forty seconds.
Fry in hot fat until a golden brown; use a frying basket and fry only four or five at a time; more will cool the fat.
Drain on soft paper and serve immediately.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavour and the flaked body of the balls.
- Potatoes
- Starch that mashes light and binds the fish into a cohesive mixture.
- Egg
- Binds the mixture so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Frying at the right temperature. Fat that is too cool lets the balls soak up oil and turn greasy, while frying only four or five at a time keeps the fat hot. The test with a raw potato checks that the fat is hot enough to brown the balls quickly and evenly.
