Half cover the joint with water and set it off, return many hours later. Best joints are the cheaper ones that have loads of flavour but are a bit tougher, neck, shoulder and shin. Browning everything helps, it doesn't keep the colour but it does help make a nice starter gravy around the joint.
Lamb being fattier can take a bit longer, Pork belly is the same, but most pork joints take slightly less.
