Input: Consider Input: I love little white kernels of popped corn.  This was good stuff, but I think I'll try a larger white kernel to pop next time, my preference.

Output: 4


Input: Consider Input: I don't know why this flour isn't available in grocery stores in the Midwest.  Typical grocer flours have a protein content much too high to give an authentic taste to such foods as pizza crust and homemade pastas.  And after years of making homemade pastas and trying to find that perfect recipe that would result in those served in the best Italian restaurants in the US and Europe, I'm happy to discover, the secret was in the 00 protein content all along.  What a fabulous difference this flour makes!  Freezes well too.

Output: 5


Input: Consider Input: Initially, the flavor is fairly accurate, however weak- from there, the flavor diminishes rapidly. I just timed it, and this gum goes flat within 5 minutes. In light of my experience, I find these rave reviews somewhat... amusing; one reviewer even went as far as to describe it as "incredibly tart". Meh. Like many new products in the realm of gum, pop, energy drinks, and fast food, they only need you to buy one. If everyone does that, they'll be sitting pretty. Based on this experience, I have no desire to try the other flavors of Extra Dessert Delights. Three stars = It's OK, but doesn't live up to the hype.
