Best Margarita?

[Guest guest]

I just offered to take my Vitamix to go hang out with a couple of friends on

Friday night and offered to make slushy margaritas. The only problem is - I've

never made a margarita in my Vitamix! I need help - recipes and tips for making

it cold and slushy! Would prefer an " all natural " margarita... I was thinking

of starting with the " perfect whole fruit margarita " in the Vitamix book and I

just watched this video:

Any advice on what I could replace the sugar with - ???

Any advice is appreciated!

Thanks in advance,

Bobbie
