Why it works: Pepper and parsley 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 provide its body and substance.
- Egg yolk
- Thickens and enriches the sauce as it is stirred in and gently heated.
- Béchamel sauce
- Adds creaminess and body, helping bind the lentils together.
- Cream
- Adds richness and a smoother, silkier texture to the mixture.
- Butter
- Adds fat and flavour, both for cooking the lentils and sautéing the onion.
The step that matters
Stir in the egg yolk quickly. Egg yolk thickens by gentle heat, but if the mixture is too hot or left too long it can scramble and curdle. Stirring quickly spreads the yolk evenly and keeps it smooth.
