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
- Under-done beef
- Provides the meat that is gently warmed through in the sauce without toughening.
- Butter
- Adds richness and carries the onion and parsley as they soften.
- All-purpose flour
- Thickens the broth into a smooth, lightly bodied sauce.
- Egg yolks
- Enrich and thicken the sauce when gently heated, giving it a silky texture.
- Port wine
- Adds sweetness and depth of flavour to the sauce.
- Vinegar
- Adds acidity that brightens the rich sauce and balances the sweetness of the port.
The step that matters
Adding the egg yolks. Egg yolks thicken when heated gently but scramble if they boil. Stir quickly over moderate heat and keep the sauce from boiling, or it will curdle and turn grainy.
