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
Preheat your oven to 400°F (200°C).
Lard the partridges by threading thin slices of fat salt pork through the skin using a larding needle.
Roast and make the gravy
Roast the partridges for 30 minutes.
In a saucepan, melt the butter over medium heat. Stir in the flour and cook until it turns dark brown.
Gradually add the boiling water, stirring constantly.
Season the gravy with salt, pepper, and the drippings from the partridges.
Stir in the currant jelly 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 the larding keeps moist and flavourful as it roasts.
- Butter
- Fat for the gravy roux, carrying flavour and helping the flour cook smoothly.
- All-purpose flour
- Thickens the gravy with the butter, and cooking it until dark brown adds colour and nutty flavour.
- Currant jelly
- Adds sweetness and a fruity tang that balances the rich gravy.
- Fat salt pork
- Lards the birds, basting the lean meat with fat as it roasts.
The step that matters
Cooking the flour until dark brown. Cooking the butter and flour together, stirred, builds the roux's colour and nutty flavour; stopping too early leaves a pale, raw-tasting gravy, while going too far burns it and tastes bitter.

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.
