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 ↓

Vegetable Stock for Soups

Ingredients

Directions

  1. Combine all ingredients in a large pot with 2 quarts of cold water.

  2. Bring to a boil, then reduce heat and simmer for 3 to 4 hours, skimming off any foam that forms on the surface.

  3. Strain the mixture to remove solids and let it stand.

  4. Pour off the clear liquid, leaving sediment behind.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Haricot beans
Break down during simmering to add body and thicken the stock.
Split peas
Dissolve partly as they cook, adding body and a fuller texture to the liquid.
Turnip
Releases sweetness and mild flavor into the long simmer.
Onion
Adds savory depth and aroma as it softens and gives up its flavor.
Carrot
Contributes gentle sweetness and color to the stock.

The step that matters

Skimming the foam. Foam rising during the boil carries impurities and proteins that can make the stock cloudy and taste bitter. Removing it as it forms keeps the liquid clear and clean-tasting.

Swap the peas

How well each one fits the dish's main ingredients (beans, turnip, onion, carrot, celery, parsley, pepper):

  1. Lentilsfits better
  2. Chickpeafits better
  3. Black-eyed peafits better
  4. Peasthe original

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