How long to roast small lamb shoulder joint?

[Wambsgans]

I've got a lamb shoulder (bone in) from butchers, 1.08kg. I want to follow this recipe which says 4 hours total cooking time for a 2.5kg piece of meat

How long should i do it for the smaller size? Is it 1 hour per 500g plus 30 mins? Which would be 2.5 hr total. So with foil for about 2 hours and without for half an hour?

I normally just do a rolled shoulder joint but wanted something more tender! Worried it'll shrink too much now as well, although it's just for 2 adults and 2 small children, but leftovers would be nice...

Lamb is only about 20 minutes per pound so at about 2.5 lb I would say 45 minutes at 180C.

If it’s a shoulder, a fair bit of that weight is bone so don’t bank on leftovers.

Still scrummy, but.

Slow roast for 3 hours at 150C

I usually do it in a roasting bag with garlic and rosemary and it's lush.

Thanks - will try tomorrow!

I cooked a half-shoulder of lamb last week. You need to cook it long and slow, and don't expect it to have a lot of meat on it. We don't eat a huge amount of meat so it was fine for three of us with a few leftovers for another time. I used this Tom Kerridge recipe. I thought it looked like a long time in the oven but it needed all that and possibly a touch more. The potatoes were gorgeous. I did lots of other vegetables too. Could have had beans or lentils to bulk things out.

20 mins per lb plus 20 mins for a medium. I sear mine first too.

Oh duh shoulder! I’d cook it in my pressure cooker, slow and low.

Well it's gone in at 150c, hopefully 3 hours should be enough... it's not a huge piece of meat so I'm assuming 3/4 of the cooking time Jamie gave for a 2x size should be plenty of time....!
Definitely intending it to be a slow roasted thing!

Hmm, at nearly 3 hours the meat looks a fair way off from 'falling off the bone' , although looks edible. I'll give it another half an hour or so but the DC want feeding...
It doesn't actually look like there's much bone in there after all, so that might have changed things a bit.

How did it turn out, @Wambsgans? I wished I'd given mine four hours rather than three, but I had the temperature at 130, not 150.

It was nice actually! A bit longer might have been better but I'd definitely do it again.
