Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Noodle Soup
Ingredients
Directions
Make the dough
Beat the eggs for one minute and mix with water and salt.
Add enough flour to form a stiff dough and knead for 15 minutes.
Roll the dough into a thin sheet and cut half into long strips less than ½ inch wide.
Cut the strips into pieces about 4 inches long.
Roll the other half of the sheet tightly into a scroll and cut into wheels less than ¼ inch wide.
Lay the noodles in a sunny window to dry for 2 hours.
Make the stock
For the stock, boil beef bones, mutton bones, and ham in 3 quarts of water with onion, carrot, and herbs.
Boil down to 2 quarts, strain, cool, skim, and season.
Cook and serve
Add a handful of noodles to the boiling stock a few at a time and simmer for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add richness and structure to the noodles.
- Flour
- Forms the gluten network that gives the dough its chewy, stiff structure.
- Beef bones
- Release gelatin and flavour into the stock, giving body and depth.
- Mutton bones
- Add gelatin and a richer, savoury flavour to the stock.
The step that matters
Add the noodles a few at a time. Adding too many noodles at once drops the stock's temperature and lets them clump and stick together, so they cook unevenly.
Swap the carrot
How well each one fits the dish's main ingredients (egg, flour, beef, mutton, ham, onion):
- Leekfits better
- Chivefits better
- Asparagusfits about as well
- Carrotthe original
Fit is the average pairing score against egg, flour, beef, mutton, ham, onion. Candidates are from the same food group and used in at least 100 recipes.
