Why it works: Ketchup and sugar match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 260 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Pheasants and Partridges
Ingredients
Directions
Roast the birds
Spit and lay the pheasants or partridges down.
Dust them with flour.
Baste often with fresh butter, keeping them at a distance from the fire.
Roast for about 30 minutes.
Make the gravy
Place the scrag of mutton in a saucepan for the gravy.
Add lemon pickle, ketchup, and browning to the saucepan.
Melt sugar and butter in a frying pan over a clear fire until frothy to make browning.
When the browning is deep brown, gradually add red wine while stirring continuously.
Add Jamaica pepper, cloves, shallots, mace, salt, and lemon rind.
Boil slowly for 10 minutes.
Pour the gravy into a bowl and let cool.
Remove the scum from the gravy.
Strain the gravy.
Bottle the gravy for use.
Serve
Serve the birds with gravy and bread sauce.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pheasants or partridges
- Provide the main meat, which is roasted until cooked through.
- Fresh butter
- Basting adds fat that carries heat to the surface and helps the skin brown and stay moist.
- Red wine
- Adds acidity and depth of flavour to the gravy as it reduces.
- Scrag of mutton
- Gives the gravy a rich, meaty body and savoury flavour.
- Sugar
- Caramelises with butter to form the dark browning that colours and flavours the gravy.
- Shallots
- Add mild sweetness and savoury aroma to the gravy.
The step that matters
Cooking the browning. Sugar and butter must be heated until deep brown but not burnt. Under-cooked browning gives pale, weak colour, while scorched sugar turns bitter and spoils the gravy.
