Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted with flour to form the roux that thickens the sauce.
- Flour
- Thickens the butter and milk into a smooth, creamy sauce.
- Milk
- Forms the liquid base of the sauce, which thickens as it cooks.
- Mushrooms
- Provide the main earthy flavour and soft, tender texture.
- Chipped beef
- Adds salty, savoury flavour and a chewy texture to the sauce.
- Eggs
- Yolks help enrich and thicken the sauce; chopped whites add body.
The step that matters
Cooking the flour and butter with the yolks until smooth. Stirring the flour and butter into a smooth paste before adding liquid prevents lumps, and the sauce must then cook while stirring so the starch thickens evenly without scorching.
