Why it works: Parsley and carrot 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 ↓
Stock, or Pot Au Feu
Ingredients
Directions
Combine 2 ½ pints of cold water with 1 pound each of bones and meat in a pot.
Add an onion, parsley, carrots, and a small amount of turnips and celery.
Do not let the mixture boil for the first 30 minutes; then simmer for 4 to 5 hours.
Skim the surface frequently to remove scum.
Season with salt sparingly, adding more at the end if needed.
Strain the stock before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones
- Release gelatin and savoury flavour into the cold water as they slowly simmer.
- Meat
- Contributes savoury flavour and richness to the broth during the long simmer.
- Onion
- Adds sweet, savoury aroma that gives the stock depth.
- Carrots
- Add gentle sweetness and aroma to the broth.
The step that matters
Keep the mixture from boiling for the first 30 minutes. Starting in cold water and heating gently lets proteins and fats release slowly, so the stock stays clear; boiling early makes it cloudy and greasy.

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