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 ↓
Soup Stock
Ingredients
Directions
Make the stock
Combine beef shin and cold water in a large pot and cook for 2 hours, gradually bringing to a boil.
Add chopped vegetables, bay leaf, cloves, mace, celery, and parsley once boiling.
Simmer the soup for at least 5 to 6 hours, covered tightly.
Strain and cool
Strain the soup into a large earthenware vessel and let it cool uncovered; the fat will help preserve the stock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shin
- Releases collagen and flavour into the water, giving the stock body and richness.
- Carrot
- Adds sweetness and aromatic depth to the stock as it simmers.
- Onion
- Contributes savoury sweetness and aroma as it cooks down in the liquid.
- Turnip
- Adds mild sweetness and a soft earthy background to the stock.
The step that matters
Bring the pot to a gentle simmer, not a hard boil. Vigorous boiling emulsifies fat and clouds the stock, while a slow simmer keeps it clear and lets collagen dissolve gradually into a richer liquid.
Swap the mace
How well each one fits the dish's main ingredients (beef, carrot, turnip, onion, clove, celery, parsley):
