I made this for my family as no less than three family members were doing the keto diet at the time and I was basically torturing them each week with my regular ice cream batches and photos. The Keto diet is very restrictive on carbs so that rules out any normal ice cream recipe that has a lot of sugar but they can have high fat foods so that sets the stage for an ice cream recipe that includes a good amount of cream but substitutes sugar for artificial/natural sweetener. The downside of this is that regular sugar contributes important properties to the texture of the ice cream and the artificial/natural alternatives don't create the same affects. The result is an icier and less creamy ice cream with the taste of artificial sugar. The recipe tries to compensate for this by requiring the cream to be whipped prior to churning which helps to incorporate additional air. 

Compared to normal ice cream it's definitely lacking which is why I've given it a 3/5 rating overall, but considering the challenges of producing a recipe for the Keto diet, the author has actually done pretty well so as far as Keto ice cream is concerned I've given it a 4/5.

The two ice cream makers I recommend are the Cuisinart ICE-70 and the Breville BCI600 XL. Click the images below to read more about those two machines or check out my complete guide to ice cream makers to see all the options and read the pros and cons of each.
