Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Green Pea Soup
Ingredients
Directions
Make the broth
Boil the empty pods of the peas in the water for 1 hour.
Strain out the pods and add the beef.
Boil slowly for 1.5 hours.
Finish and serve
Half an hour before serving, add the shelled peas.
Twenty minutes later, stir in the rice flour, salt, and pepper. Stir frequently to prevent scorching.
Strain into a hot tureen.
Garnish with chopped parsley if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Breaks down during long simmering to give the soup body and savory flavor.
- Green peas
- Provide the main flavor and color, and their pods add sweetness to the broth.
- Rice flour
- Thickens the simmering liquid so the soup becomes smooth and fuller.
The step that matters
Stir frequently after adding the rice flour. Starch settles on the bottom of a pot of thickening liquid and scorches easily over heat. Frequent stirring keeps it dispersed, prevents a burnt taste, and lets the flour thicken evenly.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (beef, peas, rice, flour, pepper):
- Turmericfits better
- Cardamomfits about as well
- Celeryfits about as well
- Parsleythe original
Fit is the average pairing score against beef, peas, rice, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
