couldn't you use grass fed heavy cream instead of water for a primal bulletproof treat?
I just used coconut oil, I secretly suspect MCT oil is just refined coconut oil. LOL With enough vanilla I think it could be fine without sweetener, but that's just me.
Consistency was great, i added water by the drop until it got to the texture I wanted. Think you could just freeze a stir repeatedly until frozen. I picked up a hand crank ice cream maker at goodwill for $4.00.
