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 down the birds.
Dust them with flour.
Baste often with fresh butter, keeping them at a distance from the fire.
Roast for about 30 minutes.

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 cooks through over the fire while being basted.
- Flour
- Dusted on the birds to help form a light coating that browns during roasting.
- Fresh butter
- Basting fat that moistens the birds and promotes even browning on the skin.
- Mutton
- Cooked in a saucepan to give the gravy its meaty body and flavour.
- Lemon pickle
- Adds sharp acidity and tang to the gravy.
- Browning
- Adds deep brown colour to the gravy.
The step that matters
Keeping the birds at a distance from the fire. Too close a fire scorches the flour and butter coating before the birds cook through. Basting often at a gentler distance lets the heat penetrate slowly and keeps the skin moist and evenly browned.

Fit is the average pairing score against pheasant, flour, butter, mutton, ketchup, bread, sauce. Candidates are from the same food group and used in at least 100 recipes.
