Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped to stiff foam, it gives the cheese mixture lightness and helps the balls hold their shape.
- Grated cheese
- Provides the main flavour and body, and melts and browns during frying to form the crust.
- Deep lard
- Conducts heat around the balls, cooking them quickly and browning the outside.
The step that matters
Whipping the egg white until very stiff. Stiffly whipped egg white traps air, which gives the balls a light texture. If it is under-whipped, the mixture will be dense and may not hold its shape well in the hot fat.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, cheese):
- Capsicumfits better
- Asparagusfits about as well
- Mustardthe original
- Spinachfits about as well
Fit is the average pairing score against egg, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
