Example Input: We cant say enought about the Gluten Free Bisquick.. My husband and all three kids are allergic to Wheat and we are on a strick Gluten Free diet in our house.. I have tried every product out there to make pancakes, waffles, biscuits and even chicken fingers and was so pleasantly suprised that this little box does it all and does it all WONDERFUL... Pancakes are wonderful, Waffles are Great, Chicken Fingers are the best Ive made and the biscuits are delish.. Cant ask for anything better.. I only wish you could buy it ina bigger box and it was a little cheaper but we are a HUGE fan...
Example Output: 5

Example Input: Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.
Example Output: 5

Example Input: If you need gluten free, non-dairy and no egg, pickings are pretty slim.  If you use a really sharp serrated knife and work carefully, you can split them successfully.  Great for mini-pizzas!
