Ex Input:
I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.

Ex Output:

I bought this at a local gas station near my house and was excited to try it because I see it everywhere. It was nasty. I will never drink this crap again, I don't care how "good" it is for you. The taste is disgusting and I'd rather just drink regular water. Blah!

I was so excited to see gluten-free Bisquick. My grandmother and mother both used it. I fondly remember their strawberry shortcake, so that was the first thing I made. I almost cried, it was so good. I have since made the pancakes (yum yum) and baked chicken. I'm a regular at their web site, liveglutenfreely.com for its great recipes. Thank you, Bisquick!
