Yum! I halved this recipe so it would fit in my ice cream maker, but I left the rum at 1/4 cup (shhh) as I love the flavor. I also added some raisins, as I have a lot and I love rum raisin ice cream! I think the raisins actually took away from the rest of the ice cream; they were kind of tough (probably too dry) but better raisins might make this the perfect rum raisin ice cream! I loved the flavor the buttermilk added to this recipe. Great!
