My ham went well on Easter. But, I did discover that 10 hours on high in a large crockpot would be better than 8 hour. Ours was in the crock pot for 8 hours this Easter. It was very good. But, not as good as my first ham a while back that was cooked for 10 hours.
So: Cooking time for Crock Pot Ham: 10 hours.
I wrote a recipe for how I fix it a while back here: http://makingthingsstretch.blogspot.com/2013/01/crock-pot-ham.html
If you tried it, I hope it turned out well!
