It isn’t Easter without ham, but carving one can be tricky. Try a shank cut; it has a small bone (which adds flavour in the oven) and is easy to carve. Or go with a pre-sliced spiral-cut ham.
Most supermarket hams are fully cooked (it will say so on the label) and only need to be heated through. This takes about 15 min per 1 lb (500 g).
