Why no Alix, the limes we grow HERE in North Carolina are so sweet you wouldn't believe it!!!!! It's a real sugar rush!
Jenny - buttermilk is fat free - I've never seen it any other way. I just don't understand drinking it at all = it is some nasty stuff. My Dad always broke up cornbread and put buttermilk over it in a bowl. Around here if you are sitting at the lunch counter of this one place, and other places too - if you order milk they will ask if you mean "sweet" milk as so many people drink buttermilk.
It's good for cooking/recipes but I have never developed a taste for it just plain.
