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
Ingredients
Directions
Make the stock
Boil the empty pods of the peas in the water for 1 hour before adding the beef.
Strain out the pods, add the beef, and boil slowly for 1.5 hours.
Finish the soup
Half an hour before serving, add the shelled peas.
Twenty minutes later, add the rice flour, salt, and pepper.
Stir frequently to prevent scorching.
Strain into a hot tureen and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Adds savoury meaty flavour and substance to the soup as it simmers.
- Green peas
- Provide the main flavour, sweetness and body of the soup.
- Rice flour
- Starch that thickens the broth so it becomes smooth and creamy.
The step that matters
Stir frequently after adding the rice flour. Starch thickens the liquid and settles on the base of the pot, where it scorches quickly and leaves a burnt taste throughout the soup. Constant stirring keeps the starch suspended and evenly heated.
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.
