Example Input: Makes pretty good cocoa and a lot easier than on the stovetop.  Not as sweet as I would prefer and needs to be stirred to keep it in suspension.  I guess I can add marshmallows:-)
Example Output: 3

Example Input: Good quality nectar.  Very tasty.  However, I was expecting 46 fluid ounces, not 46 ounces in weight.  I find that 46 ounces in weight makes about 32 fluid ounces.
Example Output: 4

Example Input: I like this bread, and several other flavors in this brand.  This one and the seven grain are my favorites.  They bake consistently well in my Wolfgang Puck machine.  Recommended!
Example Output:
