Ingredients
Directions
Prepare the leg
Trim the underside of the leg of mutton to make it flat without exposing the bone.
Place the trimmed leg in a pot with 1 quart of water.
Stew the leg until the water is reduced by half.
Cool the broth. Skim the broth. Season the broth. Reheat the broth.
Lard the upper side of the meat with slender strips of fat.
Make diagonal incisions in the meat and insert fat using your fingers.
Roast and baste
Rub the meat with hot butter and vinegar.
Allow excess butter and vinegar to drip into the pan.
Pour 1 pint of boiling gravy over the leg.
Roast the leg for 12 minutes per pound.
Baste the leg every 10 minutes while roasting.
Glaze and serve
Before serving, pour off the fat from the gravy.
Mix a few spoonfuls of the brown juice with currant jelly and browned flour. Wet the mixture with cold water.
Baste the meat with this mixture until a fine brown glaze forms.
Serve the well-skinned gravy in a boat.

Butter and flour 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
- Leg of mutton
- Is the main cut that is larded, roasted and glazed as the centerpiece.
- Fat for larding (in the method)
- Strips inserted into the lean meat add moisture and richness as they melt during roasting.
- Hot butter
- Coats the surface, adding richness and helping the meat brown during roasting.
- Vinegar
- Adds acidity that brightens the rich meat and flavor of the butter.
- Currant jelly
- Adds sweetness and gloss to the glaze, helping it brown in the oven.
- Browned flour
- Thickens the mixture and deepens the color of the glaze and gravy.
The step that matters
Basting the glaze until it browns. The glaze mixture contains sugar from the jelly, which browns quickly at high heat. Too little liquid or too much heat can scorch it before it forms an even, fine brown glaze.
