Example Input: When I first found out that my 4 year old I had to go Gluten free I was a little worried about how she would handle it. GF Bisquick has made it a lot easier. I have been able to make her favorite foods such as chicken fingers, corn dogs, pizza and chinese (sweet and sour chicken)with this mix. Pancakes are also a big hit in our house. They have quick and easy recipes on the box. For the chinese- I take their chicken finger recipe and cute the pieces of chicken into bite size pieces, and bake according to the recipe. Cook up some rice and just use a GF sweet and sour sauce a quick simple easy meal that tastes wonderful!

Example Input: I've subscribed to receive Pamela's GF cookie mix and after the second delivery of OLD mixes I am returning to buying them in the store.  All of the last mixes during the last several months (6 bags per order x 2 = 12) have been OLD -- not expired, but the chocolate is dried up, light brown and crumbles to a powder.  I discovered it's not possible to return a subscribe 'n save order (for some reason) so I have to throw out the chocolate chips and use Ghiradelli instead.  Whenever I have bought Pamela's from Whole Foods the chocolate in the mix has been dark brown, fresh and never has crumbled to powder.  AVOID subscribe and save on this item.  Buy them in a store.
