Why it works: Lentils and shallot share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 20 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lentil Potage
Ingredients
Directions
Bring 2 quarts of water to a boil in a large pot.
Add ½ pint of lentils, 1 onion, 1 head of garlic, 1 shallot, 1 sprig of parsley, 1 bay leaf, 3 cloves, and 1 teacup of salad oil or 3 ounces of butter.
Season with pepper and boil for 2 hours.
Stir frequently to prevent burning.
Add 3 ounces of rice and 1 pound of chopped, par-boiled spinach.
Continue boiling for another 2 hours or until everything is thoroughly cooked.
Add salt just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Provide the main body and thickening of the soup as they break down during long simmering.
- Rice
- Adds starch that thickens the soup and gives it a fuller, heartier body.
- Spinach
- Adds leafy texture and color; it is added late so it stays tender rather than overcooked.
- Salad oil or butter
- Adds fat for richness and mouthfeel, carrying flavor through the soup.
The step that matters
Stir frequently during the long boil. Lentils and starch settle and stick to the bottom of the pot over two hours of simmering, which can scorch the soup and give it a burnt taste. Regular stirring keeps solids suspended and heat even.
