Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Provide the rich, crumbly base that the paste and shaped balls hold together around.
- Raw egg white
- Binds the pounded yolk paste so the balls keep their shape while frying.
- Flour
- Forms a dry outer coating that helps the balls brown evenly in the butter.
- Butter
- Conducts heat into the coating and adds browning and rich flavor as it fries.
The step that matters
Frying the coated balls. Butter browns quickly because its milk solids darken fast at frying heat. Too much heat or too long in the pan scorches the flour coating before the centers warm through, so keep the heat moderate and turn the balls often.
