How long to roast joint of ham?

[mariasgotabrandnewbag]

I have a joint of ham weighing 2kg
so far its been simmering in water for 60 mins. How much longer to simmer for and then How long should I roast for?

I do 20 mins per pound plus 20. So that's umm, 100 mins total for 2kg? Ish? So I'd put it in the oven now for 40 mins. Don't forget to save the water when you strain it (if you were intending to).

You may want to check my maths...

I boil mine for 25 mins per half kilo. Let it cool a bit then cut off the skin, glaze and bung it back in the over for about another 30 minutes until the sugar glaze has melted and browned.

A 2kg ham will be done boiling in 2 hours.
