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 ↓

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 soften into a tender, thick stew as they simmer.
- Bacon
- Adds smoky, salty fat that flavours the lentils as it renders into the stew.
- Pearl barley
- Boiled into the cooking liquid to add body and a mild, starchy thickness.
- Onion
- Adds savoury sweetness and aroma as it gently cooks with the lentils.
The step that matters
Simmer until the lentils are thoroughly cooked. Lentils must be fully tender before serving; undercooked lentils stay firm and chalky. Gentle simmering softens the starches evenly without breaking the lentils apart.
Swap the onion
How well each one fits the dish's main ingredients (lentils, parsley, barley, clove, pepper):
