Why it works: Leek and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cow's Head Soup
Ingredients
Directions
Prepare the head

Place the cow's head in a large pot that holds about 4 gallons.
Simmer the soup

Boil the soup gently for at least 4 hours, skimming occasionally.
Serve
Serve the meat and larger pieces of vegetables separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cow's head
- Provides meat and gelatin that give the soup body and richness as it simmers.
- Peas
- Thicken the broth as their starch softens during the long simmer.
- Carrots
- Add sweetness and color to the broth as they soften.
- Onions
- Contribute savory depth and aroma to the broth.
The step that matters
Skimming during the long simmer. Boiling rather than gently simmering breaks up fat and scum into the broth, making it cloudy and greasy. Skimming removes impurities that rise to the surface, keeping the soup clear and clean-tasting.
Swap the peas
How well each one fits the dish's main ingredients (carrot, celery, onion, leek, turnip, thyme, pepper):
- Lentilsfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against carrot, celery, onion, leek, turnip, thyme, pepper. Candidates are from the same food group and used in at least 100 recipes.
