I use my Vita Mix to make ice cream.
I can of coconut milk- about 340 mil I think -a Tsp of vanilla, 2 to 2 1/2 cups of frozen blue berries and strawberries, a small amount of real maple syrup. About 45 seconds later, beautiful soft serve ice cream.
Sometimes rather than Maple syrup I use local honey and once I used a 1/4 cup of sugar- (it is within my 20%) you easily use stevia as well. You can also skip the sweetener depending on your taste.
My SO who isn't into coconut milk or other 'paleo' stuff thinks it is wonderful.
