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
Soak the lentils in tepid water for about 3 hours, changing the water as it cools.
Melt 1 oz. of butter in a stewpan; lightly fry the onion.
Cook the lentils
Add the drained lentils, cover with warm water, and season with salt and pepper.
Cook gently for about 2 hours until the lentils are tender.
Remove the lid and let the water evaporate until the lentils are dry.
Finish and serve
Add the remaining butter, white sauce, and parsley; season to taste.
Toss over the fire until thoroughly hot, then serve.

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 stew, softening into a tender, thick texture as they cook.
- Butter
- Adds richness and fat, carrying flavour and giving the finished stew a smooth mouthfeel.
- White sauce
- Adds moisture and creaminess, helping bind the lentils into a cohesive stew.
- Onion
- Provides aromatic flavour when lightly fried in butter at the start.
The step that matters
Remove the lid and let the water evaporate until the lentils are dry. Evaporating the cooking liquid concentrates flavour and prevents a watery result. Stopping too early leaves the stew soupy, while over-reducing can scorch the bottom of the pan.
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.
