Why it works: Celery and pepper 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 base
Combine the milk and rice in a double boiler.
Cook slowly for 30 minutes, keeping the boiler covered.
Cook the vegetables
Slice the onion.
Cook the onion with the butter in a frying pan until tender but not brown.
Add the celery to the onion.
Transfer the mixture to the double boiler.
Add the bay leaf.
Cover and let it sit on the back of the stove for 15 minutes.
Finish the soup
Press the mixture through a puree sieve.
Return it to the boiler.
Season with salt and pepper.
If the soup is too thick, add more milk to achieve the desired consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Starch that thickens the milk as it cooks and gives the soup its body.
- Milk
- Forms the liquid base and, with the rice, creates the soup's creamy texture.
- Butter
- Fat that softens the onion and carries flavor into the soup.
- Onion
- Adds aromatic sweetness and savory depth as it softens in butter.
- Celery
- Contributes a mild, herbal aroma to the soup base.
The step that matters
Cooking the onion until tender but not brown. Browning changes the onion's flavor from mild and sweet to toasted and sharp, which would alter the soup's delicate, creamy taste. Gentle cooking softens the cell structure so the onion purees smoothly.
Swap the onion
How well each one fits the dish's main ingredients (rice, milk, butter, celery, pepper):

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against rice, milk, butter, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
