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 ↓
Cow-heel Soup
Ingredients
Directions
Prepare the broth
Clean and scald the cow-heel, then divide it into 4 parts.
Place the cow-heel in a large pot with the cold water and add a good pinch of salt.
Bring to a boil, skim off any foam, and add the chopped onion, carrot, and celery.
Let the mixture simmer gently for 3 hours or longer.
Strain the broth and season to taste.
Finish the soup
Remove some meat from the bones, chop it into small pieces, and return it to the broth.
Bring the broth to a boil again and stir in the sago or crushed tapioca.
Boil for another 25 minutes, then serve with chopped parsley and lemon juice added just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cow-heel
- Gelatinous connective tissue dissolves into the broth, giving it body and a rich mouthfeel.
- Sago or crushed tapioca
- Starch that thickens the broth as it boils.
- Onion
- Aromatic base that adds savory depth to the broth during simmering.
- Carrot
- Adds subtle sweetness and aroma to the simmered broth.
The step that matters
Stirring in the sago or crushed tapioca. Starch grains swell and thicken when heated in liquid, but they can clump if dropped in without stirring. Stir while the broth is boiling so the starch disperses evenly and thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, parsley, lemon, pepper, nutmeg):
