    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.

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.
