Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 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
- Hard-boiled egg yolks
- Form the bulk of the balls and add rich, creamy body.
- Raw egg yolks
- Bind the mashed yolks together so the balls hold their shape.
- Wheat flour
- Adds starch that helps the mixture firm up and hold together.
The step that matters
Dropping the balls into boiling soup. Adding the balls to soup that is only simmering or cooler can make them break apart or stay loose. Boiling water sets the raw yolk and flour so the balls firm up and keep their shape.
