Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: isobutyraldehyde (malty, green).
Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Egg
- Binds the flour into a dough that holds together when grated.
- Flour
- Forms the structure of the dough, which firms up into small pieces that hold their shape in the soup.
The step that matters
Drying the grated dough. If the grated pieces stay damp, they clump together and turn gummy in the boiling soup. Drying them briefly on a board lets the surface firm so the pieces stay separate and cook evenly.
