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 ↓
Dropped Codfish Balls
Ingredients
Directions
Boil
Boil the potatoes in a pot, placing the codfish on top, and cover with boiling water. Boil for 30 minutes, then drain all the water.
Mash and mix
Mash the fish and potatoes together until fine and light.
Add the butter, pepper, and beaten eggs to the mixture and combine well.
Fry
Heat a deep pan of boiling fat.
Dip a tablespoon in the hot fat, scoop a spoonful of the mixture, and drop it into the boiling fat. Fry until brown, about 10 minutes, dipping the spoon in the hot fat each time.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savory flavor and the fish body of the balls.
- Potatoes
- Adds starch and bulk, helping the mixture bind and become light when mashed.
- Eggs
- Bind the mixture together so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Dipping the spoon in the hot fat. Wetting or heating the spoon in the hot fat keeps the sticky mixture from clinging to it, so each ball drops cleanly into the fat and forms a smooth, even shape.
