Pita crisps that I've had in the past have been really dangerous. They've been thick, hard and sharp, scraping the roof of your mouth to no end. These, on the other hand, are wafer thin, with a more natural pita like texture.
Rosemary is an interesting choice - usually to be found on gastro-pub fries, your roast potatoes or chicken, but on pita chips? I'm not sure it quite fits.
The rosemary is definitely there, but so is a distinct cardboard-y element. All in all a bit bland. However I'm looking forward to trying their other flavours, because the texture is unique.
