Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cold potatoes
Form the bulk of the fritters and give them a soft, starchy interior.
Egg
Binds the mixture and, brushed on the outside, helps the cakes brown.
Butter
Fat for frying that adds richness and promotes golden browning on the surface.
Chopped onion
Adds moisture and a savoury, aromatic flavour to the mixture.

The step that matters

Fry the cakes in butter until golden brown. Butter contains milk solids that can burn before the cakes are cooked through. Medium heat and watching the colour keep the browning even without bitterness, and the shaped cakes need to be firm enough to hold together in the pan.

Swap the onion

How well each one fits the dish's main ingredients (potato, pepper, egg, butter, sauce):

  1. Capsicumfits better
  2. Chivefits better
  3. Asparagusfits better
  4. Onionthe original

Fit is the average pairing score against potato, pepper, egg, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
