The wheat flour tortilla was an innovation after wheat was brought to the New World from Spain while this region was the colony of New Spain. It is made with an unleavened, water-based dough, pressed and cooked like corn tortillas. These tortillas are very similar to the unleavened bread popular in Arab, eastern Mediterranean and southern Asian countries, though thinner and smaller in diameter. In China the "laobing" (烙餅), a thick circular "pancake", is similar to the tortilla. The Indian "roti", which is made essentially from wheat flour, is another example.
