It has a sweetness to it - but it's not as overly sweet as you might imagine, it has quite a christmassy spicy taste to it cos of the coke (I always think coke tastes quite christmassy anyway!). Equivalent I guess to having honey roast ham or something like that - in fact I would say it is slightly less sweet than that. Ok I'm waffling now.....
No the pan is fine - mine is quite new and non-stick and I've just rinsed it to do the other ham in and it's come clean.
Kim and Aggie reckon coke is good for getting pans clean anyway - gets really tough marks off (there you go, make a ham and clean your pans at the same time!)
