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 yolks
Boil the eggs for 20 minutes.
Transfer them to cold water until cool, then remove the shells.
Carefully cut through the egg whites and remove the yolks whole.
Cut the yolks into quarters or rub them into a smooth paste.
Shape the balls
Mix the yolks with melted butter, salt, and pepper.
Moisten the mixture with enough raw egg white or yolk to shape easily.
Shape the mixture into balls about the size of a nutmeg.
Roll the balls in flour.
Cook and serve
Fry in butter until brown, or drop into hot soup and cook for 5 minutes.

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
- Eggs
- Hard-boiled yolks form the body of the balls, giving them a firm, crumbly structure.
- Melted butter
- Adds richness and moisture, helping the yolk mixture hold together and feel smooth.
- Raw egg white or yolk
- Binds the mashed yolks so the mixture holds its shape when rolled and fried.
- Flour
- Dry coating that helps the outside brown and form a light crust during frying.
The step that matters
Moisten the mixture with raw egg. Cooked yolk alone is crumbly. Adding just enough raw egg binds it into a shapeable dough; too much makes it sticky and hard to fry.
