Why it works: Mutton and turkey work together. They rank in the top 7% of all ingredient pairs, and 75 recipes mention both. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
The recipe
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove the bone from the leg of mutton or ask your butcher to do it.
Fill the cavity with turkey dressing.
Cook
Place the mutton in a deep pan half filled with water and cover tightly with another pan.
Cook in a moderate oven at 350°F (175°C) for at least three hours, basting frequently.
Remove the cover.
Pour off the liquid.
Let it cool.
Skim the fat off the liquid.
Return the liquid to the pan.
Allow the meat to brown, basting often.
Finish
Before serving, add 1 tablespoon of tomato ketchup to the gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Forms the main body of the dish and provides the meat that is cooked until tender.
- Dressing for turkey
- Fills the cavity, adding moisture and flavour to the meat as it cooks.
- Tomato ketchup
- Adds sweetness and acidity to the gravy.
The step that matters
Allow the meat to brown, basting often.. Browning comes from the Maillard reaction at the surface, which needs dry heat. Basting keeps the surface moist enough to brown evenly without drying out, so the meat develops colour and flavour.

Fit is the average pairing score against mutton, turkey, ketchup. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
