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 ↓

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.

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 the fish texture of the balls.
- Potatoes
- Bind the fish together and give the balls a soft, starchy body.
- Egg
- Binds the mashed mixture so the balls hold their shape while frying.
- Butter
- Adds fat for richness and a softer, moister interior.
The step that matters
Reheat the fat after each frying. Frying lowers the oil temperature as cold food goes in. Reheating before the next batch keeps the fat hot enough to crisp the outside quickly, so the balls do not absorb excess oil and turn greasy.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, pepper):

Fit is the average pairing score against egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
