[EX Q]: The rice flour in it is a crude gritty grade (cheap?). If you've ever used Thai rice flour <a href="http://www.amazon.com/gp/product/B000EYC096">Thai Rice Flour - 16 oz</a>, you know that rice flour does not need to be this unpleasantly gritty.  I tried compensating for the grit by using Bisquick Gluten Free to make Johnny cakes since the cornmeal is sort of gritty. But sadly, after you chew you are still left with this unpleasant grit like fine sand in your mouth.
[EX A]: Negative

[EX Q]: I bought these for my vegan father who LOVES the curry kale chips by Rhythm Superfoods (my 22 month old daughter, husband and I also like them)!  Thought I would give him a new kale chip flavor--BBQ--as part of his Christmas gift. Although a different brand than we typically eat, they sounded good. First, I was disappointed to see these chips are not kale in its natural curly form but pressed into round, dog-snack-looking discs. Luckily I tried them before giving them. I spit it right out! Was it just me? My husband also tried one and couldn't finish even one chip.  I have a pack of 4 that cannot be returned... what a waste of food and money!
[EX A]: Negative

[EX Q]: ...you can absolutely forget about these. Confirmed by other reviewers, these chips are now total garbage. Like chewing on styrofoam packaging "peanuts". Positively awful, no hyperbole or exaggeration. I'll NEVER buy anything from Kettle brand ever again! From a reportedly once great "premium" brand, literally any mass market chip I've ever tried tastes better than these. Stale and rancid tasting, and virtually no salty taste whatsoever. Completely awful!
