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 ↓

Directions
Prepare the gravy
Break the meat bones into small pieces.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat bones
- Stewing them releases flavour and body into the gravy.
- Butter
- Browned with flour, it adds nutty aroma and richness to the sauce.
- Flour
- Cooked in the butter, it thickens the gravy and gives it body.
- Onions
- Stewed with the bones, they add sweetness and savoury depth to the gravy.
The step that matters
Browning the butter and flour. Cooking the flour in butter until browned builds flavour and thickens the gravy evenly. Stopping too early leaves a raw floury taste, while over-browning can taste bitter.
Swap the onion
