Failed Attempt at Coconut Ice Cream!

So my mother made this fabulous coconut ice cream on the fourth of July. Ever since then I have been craving homemade coconut ice cream. I picked up everything I needed at the store about a week ago, then came home to find that the canister of the used ice cream maker I found at a garage sale last summer was rusting on the inside! Bummer! So I borrowed a Cuisinart 2qt ice cream maker from a friend yesterday. It is one that has the canister that you freeze so that you don't use ice. First let me say that I would rather have the old ice & salt ice cream maker anyday. Even with cold ingredients the gel canister thaws out too quickly and doesn't freeze the ice cream all the way through. Second the recipe I found on-line turned out not to be as good as my mom's! It wasn't sweet enough! I was so greatly disappointed...to be craving something for a week, finally get it, & it tastes like crap! So, so disappointed, but I will live to make ice cream another day!
