Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Partridges
- Provide the main meat, which is roasted whole and trussed to hold its shape.
- Fat salt pork
- Lardons threaded through the birds baste them with fat as they roast, keeping the lean meat moist.
- Butter
- Fat that is heated and combined with flour to form the base of the gravy.
- Dry flour
- Thickens the gravy when cooked in butter until dark brown, adding colour and body.
- Currant jelly
- Adds sweetness and a fruity acidity that balances the rich pan drippings.
The step that matters
Cook the flour until dark brown. Flour cooked in butter thickens the gravy and browns it; stopping too early leaves a pale, floury taste, while cooking too long can scorch and turn it bitter.
Swap the currant

Fit is the average pairing score against pepper, butter, flour, pork. Candidates are from the same food group and used in at least 100 recipes.
