Why it works: Butter and flour 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 ↓
Egg Balls
Ingredients
Directions
Prepare the mixture
Rub the yolks of hard-boiled eggs to a paste with a wooden spoon.
Season with salt, pepper or paprika, and melted butter.
Add enough raw egg yolk or white to mold the mixture.
Roll the mixture into balls about half the size of an egg yolk.
Coat and fry
Dip the balls in slightly beaten egg white, then coat with flour.
Fry the balls in butter until golden brown.
Serve one to each person.

Butter and flour 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
- Form the base of the mixture, giving it a rich, crumbly paste texture.
- Melted butter
- Adds fat and richness, helping the mixture hold together and carrying flavor.
- Raw egg yolk or white
- Binds the paste so it can be shaped into balls.
- Flour
- Forms a dry coating that helps the outside brown when fried.
The step that matters
Frying in butter until golden brown. Frying over moderate heat lets the flour coating brown through the Maillard reaction without burning the butter. High heat darkens the butter and scorches the coating before the balls are heated through.
