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 ↓
Lamb's Head Soup
Ingredients
Directions
Prepare
Prepare the lamb's head and place it in a pot with 2 quarts of water.
Boil until the head is tender enough to remove the bones.
Cut the meat into small pieces and return it to the pot.
Simmer the soup
Add the chopped heart and liver, along with pepper, salt, onion, herbs, turnip, carrot, and celery.
Boil everything together over low heat for several hours, skimming as needed.
If the water reduces too much, add more boiling water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's head
- Provides the main meat and gelatin, giving the broth body and a rich flavor.
- Liver
- Adds deep, savory flavor and a richer, more concentrated taste to the broth.
- Heart
- Contributes dense, savory meat that adds depth to the soup.
- Onion
- Builds aromatic sweetness and savory depth as it softens in the broth.
- Turnip
- Adds mild sweetness and body as it cooks down into the soup.
- Carrot
- Adds natural sweetness and color to the broth during long simmering.
The step that matters
Skimming during the long simmer. Impurities and foam rise to the surface during prolonged boiling and can cloud the broth and taste bitter. Regular skimming keeps the soup clear and clean-flavored.
