That is a good question, and it depends more on personal preference. Some like it thicker and others thinner. I try to roll them out to about ⅛” thick. You want them thick enough they don’t break, but thin enough to not be too bready. Let me know how you do it.

Either lemon or lime juice works .

My bad, recipe has been updated. You add with pineapple and sugar.Thanks for bringing this to my attention

You can use your hands instead. You don’t want to over work the dough. A food processor is much faster and quite effective.
