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 ↓
Beef Soup
Ingredients
Directions
Make the broth
Crack the bone of the shin of beef and boil it in 4 cups of water with 1 tablespoon of coarse sea salt for 2 hours.
Skim the soup well, then add the turnips, onions, carrots, celery, and tied sweet herbs.
When the vegetables are tender, remove the meat and strain the soup back into the pot.
Finish and serve
Thicken the soup with 1 tablespoon of flour mixed with a little water.
Add chopped parsley, more salt, and pepper to taste.
For dumplings, mix 1 teaspoon of butter with 2 tablespoons of flour and moisten with water or milk.
Drop the dumplings into the boiling soup and let them cook for 5 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Releases flavour and body into the broth as it simmers for two hours.
- Flour
- Thickens the soup slightly as the starch swells in the liquid.
- Turnips
- Add mild sweetness and soft texture to the soup as they cook.
- Onions
- Add savoury sweetness and aroma to the broth as they soften.
- Carrots
- Add natural sweetness and colour to the soup as they become tender.
The step that matters
Thickening the soup with flour. Flour mixed with water first forms a smooth slurry. Added directly to hot liquid, it clumps, and the starch thickens the soup only once it is fully dispersed and heated.

Fit is the average pairing score against beef, turnip, carrot, celery, flour, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
