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 ↓
Roast Partridges
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the birds
Clean and truss the partridges.
Lard the partridges with thin slices of fat salt pork.
Roast and make the gravy
Roast the partridges in a 400°F (200°C) oven for 30 minutes.
In a basin, melt the butter until it bubbles.
Stir in the flour and cook until dark brown.
Gradually pour in the boiling water, stirring constantly.
Season the gravy with salt, pepper, and the drippings from the partridges.
Add ½ cup of currant jelly to the gravy before serving.

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 cooks through in the oven and gives the dish its body.
- Fat salt pork
- Lardons add fat that keeps the lean game moist as it roasts.
- Butter
- Fat that is cooked with flour to form the base of the gravy roux.
- Dry flour
- Thickens the gravy when cooked in butter and then mixed with water.
- Currant jelly
- Adds sweetness and fruity acidity that balances the rich gravy.
The step that matters
Cook the flour in butter until dark brown. The roux must cook long enough to develop colour and nutty flavour, but not burn. Stirring constantly prevents scorching, and the roux must be fully mixed before the boiling water goes in so the gravy thickens smoothly without lumps.
Swap the currant

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