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 ↓

Vegetable Stock for Soups

Ingredients

Directions

Make the stock

  1. Combine all ingredients in a large pot.

  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 stock to remove solids and let it stand.

Finish

  1. 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
Break down during simmering to add body and thicken the stock.
Onion
Releases sugars and aromatic compounds that give the stock savory depth.
Carrot
Adds natural sweetness and body to the stock as it simmers.
Celery
Contributes aromatic flavor compounds that build the stock's savory base.

The step that matters

Skimming the foam. Foam carries impurities and proteins that can cloud the stock and taste bitter if left on the surface. Removing it during simmering keeps the stock clear and clean-tasting.

Swap the peas

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

  1. Lentilsfits better
  2. Chickpeafits better

  4. Peasthe original

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