Why it works: Flour and egg 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 ↓
Noodle Soup
Ingredients
Directions
Make the broth
Boil the chicken until the meat separates from the bones, skimming the surface well.
Make the noodles
In a bowl, mix 1 pint of flour with 2 beaten eggs.
Add more flour until the mixture is quite stiff.
Roll the dough thin, sprinkle flour over it, and roll it up.
Cut the rolled dough into pieces about ½ inch wide.
Cook and serve
Add the noodle pieces to the boiling soup and cook for 15 minutes.

Flour and egg 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
- Flour
- Forms the dough's structure, and the extra flour keeps the stiff dough workable for rolling.
- Eggs
- Bind the flour into a dough and add richness and firmness to the noodles.
- Chicken
- Releases flavor and gelatin into the broth as it simmers with the bones.
The step that matters
Adding more flour until the mixture is quite stiff. Flour absorbs liquid from the eggs and gluten develops as it is worked, so the dough needs enough flour to hold together. Too little flour leaves a sticky dough that tears when rolled and turns gummy in the soup.
