What is the best way to cook a whole ham? How much water? Lid on or off? How do you know for how long and what temp? This is my first ham!

When I cook a spira ham in the oven for 90mins and I put cloves, brown sugar maple syrup and pineapples, and in the pan OJ and ginger ale.. and then I make a gravy with the pan juices and orange marmalade.. yummy!

Wash well place in apot big enough to cook in fill with cold water till it just comes over the ham , put 2 small peeled potatoes into pot when water boils turn to slow cooking and depending how big iti s done when you stick a cooking fork into it without a struggle if the fork eases in and out without any restriction it done ( basically when I cook a ham for 2 adults and3 teens it normally takes about 3and a half hours

Happy eating
