Mexican flour tortilla, the white one used in burritos is actually an invention of crypto jews settled in Northeast Mexico (El Reino Nuevo de Leon).
They were christians in practice you may call them Messianic Jews, they accepted Christ but they kept some traditions in cryptic rituals and objects.
Tortilla de Harina is an tropicalization of Matzo bread, but meant to be passed of as a Tortilla, mimicking Corn Tortilla used by Natives.
