Put all the ingredients in a pot under medium heat on the stove. Stir until the sugar melts. I like to use a whisk to get some air into the mix. Then, shut off the gas. Let it cool. Remove the vanilla stick (if that’s what you used). Place the mixture in the refrigerator for eight hours or overnight. Finally, mix it in your ice cream maker, according to the manufacturer’s directions. Editor’s Note: I have found that it is really important to freeze the base of your ice cream maker well to get best results. I use the ice cream maker attachment for my Kitchen Aid. I try to keep the freezer less full when I’m freezing the maker, and I might even lower the temperature on the fridge.
