Why it works: Chicken and onion 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 ↓

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.
In a pot, melt the butter over medium heat.
Add the chopped onion and sauté until translucent.
Stir in the peas and broth, then bring to a boil.
Reduce heat and simmer for 15 minutes.
Blend the soup until smooth, then season with salt and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Provide the main body and sweet, green flavour of the soup.
- Broth
- Supplies the liquid that cooks the peas and sets the soup's overall volume.
- Onion
- Sautéed in butter to build a sweet, savoury base flavour.
- Butter
- Adds fat and richness, carrying flavour from the onion through the soup.
The step that matters
Blend the soup until smooth. Blending while the peas are fully cooked breaks down their cell walls, producing a silky texture; under-cooked peas leave the soup grainy and starchy.
