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 into 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 into balls about half the size of a yolk.
Fry and serve
Coat in slightly beaten egg white and dip in flour.
Fry in butter until golden brown.
Serve one ball to each person and add to the soup in the tureen.

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 main body of the balls as a crumbly paste that holds together.
- Melted butter
- Adds richness and moisture to the yolk paste, keeping it tender.
- Raw egg yolk or white
- Binds the mixture so it can be shaped into balls.
- Flour
- Forms a dry coating that helps the egg white adhere and gives a light golden crust when fried.
The step that matters
Fry in butter until golden brown. Frying over moderate heat browns the flour coating through the Maillard reaction while the butter adds flavour. Too high a heat scorches the outside before the centre warms, and too low a heat leaves the coating pale and greasy.
