Why it works: Onion and chicken are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Cressy Soup
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the base
Melt the butter over medium heat in a pot.
Add the chopped onion and sauté until translucent.
Pour in the broth and bring to a boil.
Finish the soup
Add the chopped cress and simmer for 10 minutes.
Season with salt and pepper before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens as it cooks, building a sweet, savoury base for the soup.
- Butter
- Fat that carries flavour and adds richness to the soup.
- Vegetable or chicken broth
- Liquid that forms the body of the soup and cooks the cress.
- Cress
- Leafy green that wilts into the broth and gives the soup its fresh, green flavour.
The step that matters
Simmering the cress for 10 minutes. Leafy greens lose colour and fresh flavour when overcooked. Simmering only until the cress is tender keeps the soup bright and green.
Swap the onion
How well each one fits the dish's main ingredients (butter, chicken, pepper):
- Capsicumfits better
- Potatofits better
- Onionthe original
- Tomatofits about as well
Fit is the average pairing score against butter, chicken, pepper. Candidates are from the same food group and used in at least 100 recipes.
