Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Rice Soup
Ingredients
Directions
Make the soup

Stir in the flour until well mixed but not browned.
Add the stock, rice, chopped onion, chopped celery, and mixed herbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup slightly when stirred into the hot fat before the liquid goes in.
- Rice
- Softens during simmering and releases starch that gives the soup body.
- Milk
- Adds creaminess and mild sweetness to the finished soup.
- White stock
- Forms the liquid base that carries the flavour of the whole soup.
The step that matters
Stirring in the flour. Cooking flour in the hot fat until it is only well mixed, not browned, keeps its thickening power and a clean flavour. Browning adds a nutty taste and weakens thickening.
Swap the onion
How well each one fits the dish's main ingredients (flour, rice, pepper, celery, milk):
- Carrotfits better
- Capsicumfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against flour, rice, pepper, celery, milk. Candidates are from the same food group and used in at least 100 recipes.
