What bracha are pita chips? They are (what looks like) pieces of crunchy and flavored pita… although I’m not sure if it was made into a pita first. Would this be mezonot or hamotzei? They say that it is twice baked from a normal pita.
In principle, once baked into a pita, the berachah will be hamotzi — although deep frying small pieces can change the berachah to mezonos. If the pita is only re-baked, it will certainly retain the hamotzi blessing.
Yet, in this case the pita was baked into a crunchy snack. Crunchiness is one of the properties of pas haba bekisnin, and in particular where it is clearly a snack and not something intended for a meal, the berachah will be mezonos.
In addition, the pita is “flavored,” and there is room to assume that it was baked with ingredients other than water, again making its berachah mezonos.
Therefore, assuming that this is how the pita was initially baked, the berachah for the chips will be mezonos and al hamichyah. Please see the comments below for further clarification.
