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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- The yolks provide the bulk and rich, creamy body of the balls.
- Melted butter
- Adds fat and moisture, keeping the yolk mixture soft and smooth.
- Raw egg white or yolk
- Acts as a binder that holds the mixture together when shaped.
- Flour
- Forms a dry coating that helps the balls brown evenly when fried.
The step that matters
Rub the yolks into a smooth paste. Any lumps or unbroken yolk pieces will make the mixture crumble when shaped and give an uneven texture. Rubbing the yolks through fully breaks them down so the mixture binds evenly.
