Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Vegetable Soup
Ingredients
Directions
Make the broth
Boil the veal and beef bones in a large pot for 1.5 hours.
Season the broth with salt and pepper.
Add peas, carrot, onion, cauliflower, celery, and parsley to the pot.
Boil the soup for another 1.5 hours.
Strain the soup through a colander.
Return the strained broth to the pot and bring it to a boil.
Make the dumplings
Mix eggs, flour, and milk in a bowl to make the dumpling mixture.
Melt butter in a dish on the stove.
Stir the melted butter into the dumpling mixture until it forms a thick dough.
Let the dough cool.
Add one egg, nutmeg, sugar, and salt to the dough; stir well.
Drop tablespoonfuls of the dumpling mixture into the boiling soup.
Cook the dumplings in the soup for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dumpling dough and help it set as it cooks in the soup.
- Flour
- Forms the structure of the dumplings as the starch sets with heat.
- Butter
- Adds richness and tenderness to the dumpling dough.
- Milk
- Moistens the flour to form a dough and adds softness to the dumplings.
- Veal and beef bones
- Release gelatin and flavour into the broth as they simmer.
The step that matters
Cooking the dumplings in the boiling soup. The soup must be at a steady boil when the dumpling mixture goes in. If it is too weak, the dumplings sink, turn soggy, and cook unevenly, while a rolling boil firms the outside quickly.
Swap the peas
How well each one fits the dish's main ingredients (veal, beef, pepper, carrot, onion, cauliflower, celery):
- Beansfits better
- Lentilsfits better
- Chestnutfits about as well
- Peasthe original
Fit is the average pairing score against veal, beef, pepper, carrot, onion, cauliflower, celery. Candidates are from the same food group and used in at least 100 recipes.
