how would you make a really good mango lassie? i made one tonight using one mango, one cup of vanilla soy yogurt, some ice cubes, and a little sugar. the thought of it was much more exciting than the actual lassie, which tasted too much like the weird aspect of soy yogurt. i used whole soy yogurt, which is pretty much the only kind i've ever tried, though there seem to be a lot more brand varieties of it than there used to. i haven't tried any of these and am curious if anyone has any favorites.
