To Boil Shoulder of Mutton with Oysters
Ingredients
Directions
Prepare the mutton
Hang the mutton for a few days, then salt it well for 2 days.
Bone the mutton and sprinkle it with black pepper and ground mace.
Lay oysters over the mutton, roll it tightly, and tie it.
Stew and serve
Stew the mutton in a small amount of water with an onion and whole peppercorns until tender, keeping the stew-pan covered while cooking.
Prepare gravy and stew some oysters in it.
Thicken the gravy with flour and butter, then pour it over the mutton after removing the ties.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Long, gentle stewing turns the tough shoulder meat tender and moist.
- Oysters
- Their briny flavour seasons the rolled meat and the gravy.
- Flour
- Thickens the gravy so it coats the mutton.
- Butter
- Adds richness and a smooth body to the thickened gravy.
The step that matters
Stewing the rolled mutton until tender. Shoulder is a tough cut rich in connective tissue. It needs slow, moist heat over a long time to break down into tender meat. Keeping the pan covered holds in steam so the meat does not dry out while it cooks in a small amount of water.
