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 Cakes
Ingredients
Directions
Prepare the filling
Boil the soaked cod until cooked, then chop it finely.
Boil and mash an equal quantity of potatoes.
Combine the chopped cod and mashed potatoes.
Shape and fry
Moisten the mixture with beaten eggs or milk, and add a bit of butter and a little pepper.
Form the mixture into small round cakes and coat the outside with flour.
Heat lard in a pan until boiling hot, then fry the cakes until brown on both sides.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soaked cod
- Provides the main flavour and flaked body of the cakes.
- Potatoes
- Bind the fish together and give the cakes a soft, tender texture.
- Beaten eggs or milk
- Moisten the mixture and help bind it so the cakes hold together.
- Flour
- Coats the outside so the cakes brown evenly in the hot lard.
- Lard
- Fat for frying that browns the outside of the cakes.
The step that matters
Frying the cakes in hot lard. The lard must be boiling hot before the cakes go in. Hot fat sears the floured outside quickly, forming a crust that browns and holds the shape, while a cool pan lets the cakes soak up grease and fall apart.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, pepper, flour):
- Chivefits better
- Shallotfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against egg, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
