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 on the back of the stove for 15 minutes, then boil gently for another 15 minutes.
Boil the potatoes until tender, then mash them while hot.
Mix the filling
Mix the mashed potatoes with the codfish, seasoning with pepper and coarse sea salt.
Add the butter and stir until melted.
Beat the eggs well and stir them into the fish and potato mixture.
Fry and drain
Drop spoonfuls of the mixture into hot lard or form into balls.
Lay a napkin on a platter to absorb excess fat.

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 bulk of the filling.
- Potatoes
- Add body and softness, binding the fish into a mashable mixture.
- Butter
- Adds richness and moisture to the mixture.
- Eggs
- Bind the mixture so the balls hold together when fried.
The step that matters
Stir in the eggs well. Beaten eggs bind the fish and potato mixture; if they are not fully incorporated, the balls may fall apart or cook unevenly in the hot lard.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, egg):
