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 ↓
Egg Balls
Ingredients
Directions
Prepare the yolks
Boil the eggs for 10 minutes.
Transfer the eggs to cold water until cool, then remove the yolks.
Pound the yolks in a mortar until they form a paste.
Beat the yolks with salt, pepper, and the egg white.
Shape and fry
Form the mixture into balls about the size of a walnut.
Roll the balls in flour.
Fry the balls in butter or chicken fat until browned, being careful not to burn.

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
- Eggs
- Provide the main body of the balls, with yolks setting into a firm, paste-like mixture.
- Egg white
- Binds the pounded yolk mixture so the balls hold their shape.
- Flour
- Coats the outside so the balls brown evenly during frying.
- Butter or chicken fat
- Conducts heat for frying and adds richness and browning to the surface.
The step that matters
Fry the balls until browned, not burned. Flour-coated surfaces brown quickly in hot fat, and the sugars and proteins can scorch before the centre warms through. Moderate heat and watching colour lets the surface brown evenly without turning bitter.
“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.
