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
Cook the rice and milk
Combine milk and rice in a double boiler.
Cook slowly for 30 minutes, keeping the boiler covered.
Add the onion and celery
Melt butter in a frying pan.
Add sliced onion.
Cook slowly until onion is tender but not browned.
Add chopped celery to the onion.
Transfer the mixture to the double boiler.
Add bay leaf and cover.
Let sit on the back of the stove for 15 minutes.
Strain and finish
Press mixture through a puree sieve.
Return it to the boiler.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Its starch swells and thickens the milk, giving the soup body as it cooks.
- Milk
- Forms the liquid base and gives the soup its creamy texture.
- Butter
- Adds fat for richness and carries flavor from the aromatics.
- Onion
- Slow cooking softens it and builds a sweet, savory aroma for the soup.
- Celery
- Contributes a fresh, vegetal flavor to the base.
The step that matters
Cook the rice and milk slowly in the covered double boiler. Milk scorches easily over direct high heat. Gentle, indirect heat lets the rice starch swell and soften evenly while the milk stays smooth and does not burn.
Swap the onion
How well each one fits the dish's main ingredients (rice, milk, butter, celery, pepper):
- Potatofits better
- Carrotfits better
- 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.
