Tip: To toast corn tortillas, heat a nonstick skillet over high. Dip a tortilla in cold water and place it directly in the hot skillet. After about 30 seconds (or longer for more toasting), flip it. Remove from the skillet and cover with a kitchen towel. Repeat the procedure with the remaining tortillas. Let the covered tortillas steam about 5 minutes. The finished tortillas should be soft and moist with flaky brown spots.
