Ham is one of the things that has changed enormously on our table and in our cooking over the years. In Australia it wasn’t served very often. At Christmas the big treat was chicken, not turkey or ham which were very American and not available as they are today. The only way we saw large pieces of ham at our house was from a tin – the best brand being Mayfair.  This old recipe at first glance sounds a bit strange, but the combination of ham, mustard, ginger and pineapple could taste quite good, I think I’d top it with a bit of cheese though.  Might be worth retrying with a better quality piece of ham?
