Avocado Ice Cream

I found a recipe online for this ice cream but some of the ingredients weren't quite up to snuff for my liking so I modified it (I think it still counts as an original creation though, right?)

3 ripe avocados
2 – 3 T lime juice (depending on the strength of the lime)
1/2 teaspoon stevia, powdered or liquid
2 C MimicCream
1 C almond or coconut milk
2 T tequila (optional) make sure you use organic tequila... JK

Puree all and use ice cream maker to freeze according to your maker's directions. **OR** Cameron (my 12 year old) told me that he was taught in school to make ice-cream using two zip lock bags, some ice, and some salt (he said regular salt was fine), instead of an ice cream maker (let's face it, I don't know anyone who owns an ice cream maker except my sweet crazy niece Brit). I haven't tried it yet - BUT, he said it worked... I will get back to you after he shows me how to make this recipe using what he learned in school. Tick Tock...
