Why it works: Onion and flour are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 32,460 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Meat bone and trimmings
- Provide the main meat flavor as they brown and release juices into the gravy.
- Flour
- Thickens the gravy as it cooks, giving it body so it clings to the meat.
- Onion or salt pork
- Adds savory depth and aroma as it browns in the pan.
The step that matters
Add the thickening to the boiling gravy. Flour mixed with water must be stirred into gravy that is simmering, not cold, and then cooked a little longer so it thickens smoothly and loses its raw floury taste; adding it lumpy or to cold liquid leaves clumps.
