Why it works: Lentils and parsley match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 322 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Stewed Lentils
Ingredients
Directions
Prepare
Wash and soak the lentils in cold water for 1–2 hours.
In a pot, combine lentils with 2 quarts cold water, 1 ounce butter, eschalots, sliced onion, chopped parsley, and salt.
Simmer for about 2 hours until tender.
Drain the lentils in a sieve.
Finish and serve
In a saucepan, melt 2 ounces butter with a little flour, then add the lentils and stir well over heat.
Boil gently for 10 minutes.
Serve on a flat dish with a border of mashed potatoes or in a deep dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Form the main body of the dish and, once cooked, give it a soft, tender texture.
- Butter
- Adds richness and a smooth mouthfeel to the lentils.
- Flour
- Thickens the butter and the cooking liquid so the lentils become a stew rather than watery.
- Onion
- Contributes savoury sweetness and aroma as it softens during cooking.
The step that matters
Boil gently for 10 minutes after adding the lentils. Flour needs to be cooked for the thickening to set and lose its raw taste; a hard boil can break the lentils apart and make the stew gluey, so a gentle simmer keeps the texture intact.
Swap the onion
How well each one fits the dish's main ingredients (lentils, butter, parsley, flour):
- Shallotfits better
- Kalefits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against lentils, butter, parsley, flour. Candidates are from the same food group and used in at least 100 recipes.
