Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Piquant Pea Soup
Ingredients
Directions
Prepare the peas
If using dried peas, scald them in a solution of baking soda water, then blanch and cook in 2 quarts of water until tender.
Pass the cooked peas through a sieve.
Make the soup
Fry the chopped onions in 2 tablespoons of butter until soft.
Add the cloves and bay leaf to the onions and stir together.
Mix in the salt and tomatoes, then let the mixture cook slowly for 1 hour.
If the soup is too thick, add a little boiling water and cook a bit longer.
Finish and serve
Stir in a pinch of red pepper and 1 tablespoon of butter just before serving.
Top with fried bread squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the body of the soup, thickening it once cooked and passed through a sieve.
- Onions
- Build a sweet, savoury base as they soften in butter.
- Tomatoes
- Add acidity and body, balancing the sweetness of the peas and onions.
- Butter
- Adds fat and rich flavour to the onions and finished soup.
- Bread
- Adds crisp, golden texture contrasting with the smooth soup.
The step that matters
Passing the cooked peas through a sieve. Pushing the peas through a sieve breaks them down into a smooth purée. Leaving lumps or skins makes the soup grainy, so the peas should be cooked fully tender first.
Swap the clove
How well each one fits the dish's main ingredients (peas, onion, butter, tomato, pepper, bread):
- Garlicfits better
- Thymefits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against peas, onion, butter, tomato, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
