Fill a heavy bottomed pot with enough oil to reach 2” (5cm) up the side. Set a cooling rack over a paper towel lined baking sheet. Heat oil over medium heat to 350°F (180ºC). Working a few tortilla pieces at a time, add to the skillet and fry on both sides, about 30 seconds total. Do not add too many at a time or it will crowd the pan.
