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 ↓
Salt Codfish Cakes
Ingredients
Directions
Prepare the fish
Soak the codfish overnight.
In the morning, place the fish in a saucepan with cold water and bring to a boil.
Once boiling, reduce heat and let the fish steam without boiling.
When cooked, remove bones and drain the fish.
Make the cakes
Add the hot boiled potatoes and mash together with the fish.
Season with pepper and coarse sea salt, then mix in the beaten egg and butter.
Form the mixture into cakes and fry until golden brown.

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 flaky body of the cakes.
- Potatoes
- Mashed starch gives the cakes their soft body and helps them hold together.
- Egg
- Binds the mixture so the cakes hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Let the fish steam without boiling. Boiling toughens and dries the fish proteins, so gentle steaming keeps the flesh moist and tender for mashing.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, pepper):
- Capsicumfits better
