In a medium saucepan, heat blueberries and honey on medium-high heat until they come to a boil. Turn down heat, mash blueberries and simmer for 2-3 minutes.
Let blueberries cool at least 5 minutes.
In a Vitamix or high-speed blender, pour blueberry-honey mixture and both milks.
Blend on high until mixed well and pour mixture into a standard bread pan, cover with 2 layers plastic wrap and freeze for 20-24 hours.
 If using an ice-cream maker, complete up to Step 3 then let the mixture sit in the fridge for at least 2 hours before following the manufacturer’s instructions.
