Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- The beaten raw egg binds the mashed yolks so the mixture holds its shape.
- Flour
- A light coating dries the surface, helping the balls brown and reducing sticking in the pan.
- Butter
- Fat conducts heat in the pan, promoting even browning and adding rich flavor.
The step that matters
Frying with tossing. Frying over steady heat while tossing the balls lets the flour coating set and brown evenly. Letting them sit still can scorch one side and make the coating stick to the pan.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
