Why it works: Egg and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and 104,138 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the batter
Beat the egg yolks with the stock in a bowl.
Slowly pour the mixture into a pot with the grated cheese and flour, mixing to form a paste.
Cook and serve
In a saucepan, bring the broth to a boil.
Using a tin sieve, slowly add the paste to the boiling broth, allowing it to form vermicelli shapes.
Boil for 8 to 10 minutes, then serve.

Egg and flour share little aroma chemistry, yet 104,138 recipes mention both: they likely 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 yolks
- Provide richness and help bind the paste into a smooth, tender dough.
- Flour
- Gives the paste body so it holds its strands while simmering in the broth.
- Grated parmesan cheese
- Adds savory, salty flavour and a little extra body to the paste.
The step that matters
Pushing the paste through the sieve into the boiling broth. If the broth is not at a steady boil, or the paste is added too fast, the strands clump together instead of forming separate vermicelli. Slow, steady pouring keeps the strands distinct and lets them set in the hot liquid.
