Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentil porridge or pea brose
- Forms the moist base that holds the fritter mixture together.
- Breadcrumbs
- Absorb moisture and help bind the mixture so the cakes hold their shape.
- Onion
- Adds savoury sweetness and aroma as it cooks into the mixture.
- Butter or oil
- Conducts heat in the pan and promotes browning on the outside of the cakes.
The step that matters
Fry in butter or oil until golden brown. Frying over steady heat browns the outside through the Maillard reaction, building flavour and a crisp crust. Cakes that are too hot brown before the centre heats, while cakes that are too cool absorb fat and turn greasy.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter):
- Capsicumfits better

- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
