Input: Consider Input: We received a gift box that contained the Stonewall Farms Pancake Mix and they were out of this world. They are the lightest, fluffy and flavorful pancakes and waffles you will ever taste.  And the price on Amazon is a big savings over ordering from Stonewall Farms.  Don't shy away from the larger size and the two pack because you will devour these pancakes in no time.

Output: 5


Input: Consider Input: Ghirardelli isn't the finest chocolate you can buy, but it's pretty good, and the Intense Dark Assortment is both inexpensive, and provides you a few possibilities.  I've lately taken to unwrapping a 60%, 72% and 86% cacao square for each dinner guest and setting them on an individual saucer, to serve as an after-dinner sampler with red wine or Scotch. That's been a pretty popular approach. A similar approach also works "therapeutically"---if someone's having a bad day, sitting them down with a small assortment of increasingly intense chocolate isn't a bad path to feeling a little better.  I do wish that there were the same number of each in the bag; that's the only downside. Of course, if you really want the sets of three to serve to guests, you'll have to go through the tiresome task of somehow eating the extras. Darn.

Input: Consider Input: I have a Chihuahua that eats anything and everything- even things that are not supposed to be eaten. When these treats came, she wanted them, she could smell them when the bag opened and was going crazy for them. I gave her a biscuit and she played with it for a couple minutes and tried to eat it but she couldnt- was too big and too hard. I could NOT break it into a smaller piece by hand, they are extremely hard. I left the treat out overnight and she left it alone. A friend brought their Doberman over and she ate the treat no problem. I am rating these treats a 3 because my small dog couldnt eat them and there was no sizing info about the treat on the package and really if it wasnt for a friend having a dog the treats wouldve been trashed.
