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 ↓

Ingredients
Directions
Prepare
Break the beef, calves' feet, and veal into small pieces and wash them well.
Place the meat in a large pot with the carrots, onions, parsley, and water.
Simmer
Bring to a boil, then reduce heat and simmer until the liquid is reduced by half, skimming off fat as needed.
Remove from heat and let it sit for a few minutes.
Strain and clarify
Strain the mixture first through a colander and then through a clean cloth or rubber.
Let the strained liquid cool, then remove any fat and grease.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Breaks down into rich meat flavor and body in the simmered liquid.
- Calves' feet
- Release gelatin into the liquid, giving the finished aspic its setting power.
- Knuckle of veal
- Adds collagen and savory depth that gelatin-rich stock needs to set firmly.
- Onions
- Contribute savory sweetness and aroma to the broth as they simmer.
- Carrots
- Add gentle sweetness and aroma that balance the savory meat flavor.
The step that matters
Simmering until reduced by half. Keeping the liquid at a gentle simmer, with fat skimmed off, produces a clear, concentrated broth. Boiling hard emulsifies fat and clouds the liquid, and too little reduction leaves it too weak to set.
Swap the onion

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