Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the rissole mixture, giving it body and soft interior texture.
- Egg yolks
- Bind the mixture together so the balls hold their shape when fried.
- Butter
- Adds richness and moisture to the potato mixture.
- Flour
- Forms a dry coating that helps the outside brown and crisp in the fat.
The step that matters
Frying the coated balls in hot fat. If the fat is not hot enough, the coating absorbs oil and turns greasy before it browns. Hot fat quickly sets the outer coating so the balls stay intact and golden.
