Why it works: Parsley and leek match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 759 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Rice Soup
Ingredients
Directions
Prepare the rice
Wash the rice in cold water and drain it.
Combine the rice with 2 quarts of cold water in a pot.
Bring the mixture to a boil, stirring occasionally.
Once boiling, immerse the rice in cold water and drain it again.
Make the soup
In a saucepan, add the rice to 3 quarts of boiling broth.
Season with coarse sea salt and add the parsley and leeks.
Cover the saucepan and let it simmer until the rice is cooked.
Skim off any foam, remove the parsley and leeks, and serve garnished with chopped parsley or chives.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Provides the body of the soup as its starch softens and thickens the broth during simmering.
- Leeks
- Add a mild onion-like aroma and sweetness that flavour the broth as they cook.
- Parsley
- Adds a fresh, herbal aroma to the broth while it simmers.
- Broth
- Forms the liquid base, carrying the flavour of the whole soup.
The step that matters
Rinse the rice before cooking. Rinsing and briefly boiling then draining the rice removes surface starch and impurities, which keeps the broth clear and stops the soup from becoming gluey.
Swap the parsley
How well each one fits the dish's main ingredients (rice, leek):

Fit is the average pairing score against rice, leek. Candidates are from the same food group and used in at least 100 recipes.
