Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal kidney
- Forms the main body of the balls and gives them their rich, meaty flavour.
- Fat
- Adds moisture and richness so the balls stay tender rather than dry.
- Egg
- Binds the chopped mixture so the balls hold their shape while frying.
The step that matters
Rolling the balls with the egg. The egg is what holds the chopped kidney and fat together. If the mixture is too wet or the egg is not evenly worked in, the balls may fall apart in the pan.
Swap the leek
How well each one fits the dish's main ingredients (veal, pepper, egg):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Leekthe original
Fit is the average pairing score against veal, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
