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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the codfish
Soak the codfish for one day and night.
Boil the codfish until tender, then shred it and remove all bones.
Let the shredded fish drain.
Mix and shape
In a bowl, combine the codfish, mashed potatoes, pepper, salt, sweet milk, and egg. Mix everything well together.
Form the mixture into rolls.
Bake
Bake in a preheated oven at 400°F (200°C) until light 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 flesh and savoury flavour of the dish.
- Irish potatoes
- Add body and softness, helping the mixture hold together as rolls.
- Egg
- Binds the mixture so the rolls keep their shape when baked.
- Sweet milk
- Adds moisture, keeping the mixture tender rather than dry.
The step that matters
Remove all bones from the cooked codfish. Bones left in the shredded fish can end up in the mixture and be eaten. Shredding after boiling, while the fish is still tender, makes bones easier to find and remove by hand.
Swap the potato
How well each one fits the dish's main ingredients (pepper, milk, egg):
- Capsicumfits better
- Potatothe original
- Asparagusfits about as well
- Spinachfits about as well
Fit is the average pairing score against pepper, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
