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
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
Preheat oven to 400°F (200°C).
Spit the pheasants or partridges and dust them with flour.
Roast
Baste them often with fresh butter while 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 to the saucepan.
In a frying pan, mix sugar and butter over a clear fire until frothy.
Pour in the red wine and stir well.
Add Jamaica pepper, cloves, mace, and salt, and simmer for about 10 minutes.
Strain the gravy and set aside.
Serve
Serve the roasted birds with the gravy and garnish with a feather.

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
- Form the main dish; their meat is cooked by roasting and basted for moisture.
- Fresh butter
- Adds fat for basting, helping the birds brown and stay moist.
- Sugar
- Caramelises with butter in the frying pan, adding sweetness and colour to the gravy.
- Red wine
- Adds acidity and depth of flavour to the gravy as it simmers.
- Scrag of mutton
- Gives the gravy a rich meaty base as it cooks in the saucepan.
The step that matters
Strain the gravy and set aside. Straining removes the cloves, mace and other solids so the gravy is smooth. Sugar and butter should be cooked only until frothy, since over-browned sugar turns bitter.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
