Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
A Good Gravy
Ingredients
Directions
Prepare
Cut the skirt of beef and kidney into pieces.
Soak and clean the shank bones of mutton.
Make the gravy
In a frying pan, cook the lean beef without butter until the juices are absorbed.

Add a small quantity of water, herbs, onions, spices, and a bit of lean ham.
Simmer until rich and store in a cool place without removing the fat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Releases and then reabsorbs its juices, building concentrated meaty flavour in the pan.
- Skirt of beef
- Adds connective tissue that breaks down during stewing, giving body and richness to the gravy.
- Shank bones of mutton
- Release gelatin and marrow flavour into the liquid, contributing body and depth.
- Ox kidney or milt
- Adds savoury, rich flavour and tender texture to the stewed meat.
The step that matters
Simmer until rich and store without removing the fat. Gentle simmering lets collagen and gelatin from the bones and connective tissue dissolve slowly into the liquid, giving body. Boiling hard can make the broth cloudy and the meat tough. Leaving the fat on top helps protect the gravy from drying and spoiling while it cools.
