Baked the 5 pound (2.5 kg) lamb roast yesterday in the oven. Wanted to slow cook it but my tray wasn’t deep enough to cover it with enough water. So I browned it in the frying pan first and then baked it in the oven at 140C for 5 hrs until the core reached 60C.
Covered it with aluminum foil to prevent charring. Now I just need to reheat it tomorrow and finish the sauce.
