Heat a dry skillet or griddle over medium-high heat
Place the corn tortilla on the hot surface
Warm for about 15 to 30 seconds per side
Flip once the tortilla starts to puff or show light brown spots

Repeat with remaining tortillas
For a softer tortilla, lightly dampen it before heating
For a microwave method, stack tortillas and wrap them in a damp paper towel
Microwave for 20 to 30 seconds, checking as needed
For an oven method, wrap tortillas in foil and heat at 350°F for about 10 minutes
