Example Input: I regularly purchase this item in the bulk and loved it because it was also dairy free. However, my last purchase was disappointing, after opening a brand new package I noticed a black thing in the mix, carefully removed to find out it was a dead flour beetle! I sifted the mix and found more DEAD BUGS!  This is the second time I writing this review. Amazon didn't publish my first review. Thank you AMAZON. I will not be purchasing this item again.
Example Output: 1

Example Input: It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.
Example Output: 4

Example Input: This really is the only choice when it comes to soy and dairy free baking (unless you want to use lard).  The Spectrum shortening uses palm kernel oil and has the consistancy of regular Crisco (perhaps a little stiffer).  It seems to bake just fine and if you need to be soy and dairy free I highly recommend it.
