This is OT, but I'm curious: what do kale chips taste like to you? A little sweet? To me, they taste like lemon rind without the "lemony" taste. Just pure bitterness.
I guess there are many variants of kale chips, but never tried one that tasted particularly "lemony". They are indeed a bit bitter, but the ones I buy are mostly a fried something with lots of salt (yeah, like pretty much all chips). I do like its texture and more earthy/complex flavor, which I generally find more interesting than potato or tortilla chips alone.
I've tried 3 kinds of kale chips and disliked them all. Then again, I really dislike kale. And I like just about everything. I refer to kale as fart lettuce.
