Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provides bulk and soft body so the balls hold together without being dense.
- Codfish
- Supplies the main savoury flavour and protein that gives the balls their substance.
- Butter
- Adds richness and moisture, softening the mixture and carrying flavour.
- Egg
- Binds the mixture so the balls keep their shape while frying.
- Lard
- Conducts heat for frying and drives browning on the outside of the balls.
The step that matters
Frying the balls in hot lard. If the lard is not hot enough, the balls absorb fat and turn greasy before browning. Enough heat sets the egg and browns the surface quickly, keeping the inside tender.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
