Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Lentils, Savoury
Ingredients
Directions
Prepare the lentils
Soak the lentils in tepid water for 3 hours, changing the water as it cools.
Melt 1 ounce of butter in a stewpan.
Lightly fry the onion.
Add the drained lentils.
Cover the lentils with warm water.
Season with salt and pepper.
Cook and finish
Cook gently for about 2 hours.
Once the lentils are tender, remove the lid and allow the water to evaporate until the lentils are dry.
Add the remaining butter, white sauce, and parsley.
Season to taste.
Toss over heat until thoroughly hot.
Dish up and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Form the bulk of the stew and set its soft, tender texture as they cook.
- Butter
- Adds richness and a silky mouthfeel to the finished stew.
- White sauce
- Adds moisture and creaminess that binds the lentils together.
- Onion
- Adds savoury aroma and sweetness when lightly fried in butter.
The step that matters
Allow the water to evaporate until the lentils are dry. Lentils absorb and hold water as they cook. Driving off the excess water leaves them dry enough to take up the white sauce and butter without turning soupy.
Swap the lentils
How well each one fits the dish's main ingredients (butter, onion, parsley, sauce, pepper):
- Black-eyed peafits better
- Beansfits about as well
- Chickpeafits about as well
- Lentilsthe original
Fit is the average pairing score against butter, onion, parsley, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
