This is my mother's recipe. I have given it a twist by changing the juice flavor; peach is my favorite! I use 2 liters of juice (either peach, pineapple, or passion fruit). I change it every year. It's so good, everyone who has tasted it offers to pay me to cook theirs.
Recipe Summary test
Coat left over slices with juices! They are even better next day! I personally cook it 2 days before Christmas, carve it, refrigerate with juices, and then just heat it again in the oven on Christmas Eve. It loses the presentation, but the taste is worth it.
