Why it works: Ketchup and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Pheasants and Partridges
Ingredients
Directions
Roast the birds
Spit and lay the birds down.
Dust them with flour and baste often with fresh butter, keeping them at a distance from the fire.
Roast for about 30 minutes.
Make the gravy
For the gravy, place the scrag of mutton in a saucepan.
Add lemon pickle, ketchup, and browning sauce.
In a frying pan, mix sugar and butter over a clear fire until frothy.
When deep brown, gradually add red wine while stirring continuously.
Add Jamaica pepper, cloves, shallots, mace, ketchup, salt, and lemon rind.
Boil slowly for 10 minutes.
Pour the gravy into a bowl.
Once cold, remove the scum and bottle 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
- Butter
- Basting fat that browns the birds' skin and keeps the meat moist as it roasts.
- Sugar
- Caramelised with butter to give the gravy its deep brown colour and sweetness.
- Red wine
- Adds acidity and depth of flavour to the gravy as it reduces.
- Shallots
- Soften during simmering and add a mild savoury sweetness to the gravy.
- Flour
- Dusted over the birds to help form a browned, lightly crisp surface.
The step that matters
Caramelising the sugar and butter. Sugar burns quickly once it turns dark, giving a bitter taste. Cooking over a clear, moderate fire and stopping at deep brown keeps the colour rich without scorching, and gradually adding the wine prevents the hot caramel from spattering or seizing.
Swap the lemon
How well each one fits the dish's main ingredients (pheasant, flour, butter, mutton, ketchup, sauce, sugar):
- Raisinfits better
- Lemonthe original
- Applefits about as well
- Red currantfits less well
Fit is the average pairing score against pheasant, flour, butter, mutton, ketchup, sauce, sugar. Candidates are from the same food group and used in at least 100 recipes.
