I want to try it, but can only find it in half gallon cartons and if I hate it, I don't want to have it go to waste. How does it compare to cows milk? I love cows milk, but can't tolerate it. I'm not lactose intolerant, because I can eat yogurt and cheese no problem; just not ice cream or milk. I think it has something to do with the butter fat content. So would it be close enough to cows milk to make a good substitute?
