Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
A Bavncb of Mutton Uks Venison
Ingredients
Directions
Prepare
Hang the mutton for a week.
Pound the black and Jamaica pepper, then rub it over the mutton.
Pour the port wine over the mutton and let it marinate for five days, basting daily.
After marinating, hang the mutton for an additional four to five days, wiping it with a clean cloth three to four times a day.
Roast and finish
While roasting, baste the mutton with the marinate, adding more port wine.
A quarter hour before removing from the heat, baste with butter and sprinkle flour over it to froth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fat haunch of mutton
- Provides the main body of meat, with fat that bastes and flavours the roast as it cooks.
- Port wine
- Marinates and moistens the meat, adding sweetness and a deep fruity aroma.
- Black pepper
- Adds sharp, pungent flavour that penetrates the surface of the meat.
- Jamaica pepper
- Contributes warm, aromatic spice that complements the mutton and port.
- Butter
- Adds fat and richness, helping the surface brown and gain a glossy finish.
- Flour
- Sprinkled on the surface, it helps form a frothy, browned crust.
The step that matters
Basting with the marinade while roasting. Basting keeps the surface moist and adds flavour layer by layer, while the sugars and proteins in the port and meat brown. Too little basting can dry the outside before the centre is cooked.
