Why it works: Endive and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 284 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crumb of a 2-penny loaf
- Thickens the broth and gives the soup a smooth, body-rich texture.
- White parts of celery, endive, and lettuce
- Provide the vegetable base and mild flavor that make up the soup.
- 2 tablespoons butter
- Adds richness and a silky mouthfeel as it melts into the soup.
- 1 small french roll, grated
- Soaked in soup to add body and further thicken the broth.
The step that matters
Boil until very smooth. Thorough boiling breaks down the bread and vegetables so they blend into a uniform texture; stopping early leaves lumps and a grainy mouthfeel.
Swap the onion
How well each one fits the dish's main ingredients (pepper, clove, celery, endive, lettuce, butter):
- Leekfits better
- Mustardfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against pepper, clove, celery, endive, lettuce, butter. Candidates are from the same food group and used in at least 100 recipes.
