Lamb leg bone
Butcher's large lamb leg bone estimated at about 250 g; approximate.
Instead of Lamb leg bone
No vegetarian swap gives the body or gelatine of bone; mushroom is the closest for savoury depth.
Lamb boneUse the same weight; rinse well and simmer 1–2 hours for stock or gravy. Gives body but less meat than a leg bone.
Marrow boneUse the same weight; ask the butcher to split it. Richer and oilier, so skim excess fat from the gravy.
Lamb shankUse 1.5–2 times the weight if you need meaty body; simmer 45–60 minutes longer until tender.
Vegetarian swaps
MushroomUse about 150 g per 500 g bone; brown well for savoury depth. No gelatine body; add 10 minutes before the end.
PotatoUse equal weight; parboil and add 15–20 minutes before the end. Thickens the gravy but gives no bone flavour.
PaneerUse 70–80% of the weight; cube and add in the last 8–10 minutes. Gives bulk, not stock body.
