Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced cold roast meat
- Provides the main body and savoury flavour of the balls.
- Cold boiled potatoes
- Adds bulk and starch that helps the balls hold their shape.
- Gravy
- Adds moisture and savouriness to the mixture.
- Egg
- Binds the coating so the bread crumbs stick to each ball.
- Bread crumbs
- Forms a crisp outer layer that browns during frying.
The step that matters
Frying until light brown. Frying in fat browns the crumb coating through the Maillard reaction and crisps it. Cooking too briefly leaves the coating pale and soft, while cooking too long can dry out the cold, already-cooked filling.
