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 ↓
Stewed Lentils
Ingredients

Prepare and cook
Soak the lentils in cold water overnight.
In a stewpan, add the lentils and dripping, and simmer for 5 minutes.

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 dish and, as they cook, soften into a thick, spoonable texture.
- Onions
- Add sweetness and savoury depth as they soften into the stewing liquid.
- Dripping
- Adds fat and richness, carrying flavour through the lentils as they simmer.
- Hot water or stock
- Provides the cooking liquid that hydrates and softens the lentils.
The step that matters
Cook gently until soft. Gentle simmering lets lentil skins soften and starch release slowly, giving a creamy result. A hard boil can break the lentils apart and leave them unevenly cooked.
Swap the onion
How well each one fits the dish's main ingredients (lentils, parsley, pepper):

- Carrotfits better
- Onionthe original
Fit is the average pairing score against lentils, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
