1 | Flour tortillas. Tortillas from white flour come in different sizes and are often labeled for their intended use: burrito, fajita, etc. Esparza says that the large ones, from the state of Sonora, are sometimes referred to in slang as obaquera (sobaco means armpit) because their roughly 15-inch diameter stretches from elbow to armpit.
Use it: Depending on size, roll for burritos or fold for fajitas.
2 | Corn tortillas. Available in various sizes (often 4-inch and 7-inch diameter) and in white, yellow, and sometimes blue corn.
