Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Noodle Soup
Ingredients
Directions
Make the broth
Place the soup meat in a large pot with cold water.
Add the onion, carrots, potato, tomatoes, and chopped parsley.
Bring to a slow boil, skimming carefully, and cook for 4 to 5 hours.
Strain the broth, add salt, and remove any fat.
Make the noodles
Beat the egg with a pinch of salt to make the noodles.
Gradually work in flour until the dough is very stiff.
Flour a surface, knead the dough until smooth, then roll it out as thin as possible.
Let the noodles dry, then cut into fine shreds and spread them out to dry.
Finish the soup
Add noodles to the broth and boil for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup meat
- Releases flavor and gelatin into the water, giving the broth body and savoriness.
- Egg
- Adds richness and binds the flour into a firm, elastic noodle dough.
- Flour
- Forms the structure of the noodle dough once worked and kneaded.
- Potato
- Adds starch that lightly thickens the broth as it cooks.
- Carrots
- Contribute sweetness and aroma to the broth as they simmer.
The step that matters
Skimming the broth while it simmers. Foam and fat rising from the meat cloud the broth and can make it greasy. Skimming early and carefully keeps the broth clear and clean-tasting.
Swap the tomato
How well each one fits the dish's main ingredients (meat, onion, carrot, potato, parsley, egg, flour):
- Leekfits better
- Chivefits better
- Parsnipfits better
- Tomatothe original
Fit is the average pairing score against meat, onion, carrot, potato, parsley, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
