Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavour and the flaky, meaty body of the fritters.
- Irish potatoes
- Add starch and bulk, giving the mixture a soft, binding texture.
- Egg
- Binds the mixture together so the balls hold their shape while frying.
- Sweet milk
- Adds moisture and softness to the mixture.
The step that matters
Removing all bones from the fish. Bones left in the shredded cod are hard to notice once the mixture is formed and fried, and they can be eaten by accident. Picking the fish fully apart before combining ensures a safe, even texture throughout.
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.
