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 ↓
Codfish Balls
Ingredients
Directions
Prepare the codfish and potatoes
Simmer the codfish in a pot on the back of the stove for a little while.
Boil the potatoes until tender, then mash them finely while hot.
Mix the batter
Mix the mashed potatoes with the codfish thoroughly.
Season the mixture with pepper, coarse sea salt, and butter.
Add the beaten eggs and mix well.
Fry and serve
Drop spoonfuls of the mixture into hot lard.
Fry the balls until golden brown.
Serve the codfish balls on a napkin placed on a platter to absorb excess grease.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main salty, savory flavor and the fish body of the balls.
- Potatoes
- Mashed starch binds the fish and gives the balls a soft, tender interior.
- Eggs
- Bind the mixture together so the balls hold their shape while frying.
- Hot lard
- Conducts heat to cook the balls quickly and browns their outside.
The step that matters
Frying in hot lard. If the lard is not hot enough, the balls absorb grease and turn heavy and soggy instead of crisping. Too hot, and the outside browns before the centre cooks through. Steady heat gives a golden crust and a cooked interior.

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