Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the balls and give a soft, starchy interior.
- Butter
- Adds fat for richness and a tender, smooth texture.
- Egg yolk
- Adds richness and helps bind the mixture together.
- All-purpose flour
- Adds structure so the balls hold their shape while frying.
- Egg white
- Acts as a glue so the bread crumbs stick to the balls.
- Fine bread crumbs
- Form a crisp, golden coating when fried.
The step that matters
Fry in boiling oil until golden brown. The oil must be hot enough to crisp the crumb coating quickly. If it is too cool, the balls absorb more oil and become greasy, and the coating can separate or the centre can stay underheated.
