– Place tortillas face down. Tortillas should be placed seam side down and close to each other, so avoid unwrapping. – Don’t over-stuff the tortillas. As tempting as it is to stuff each tortilla, avoid doing so as being over-stuffed will just cause the filling to fall out. – Warm tortillas first. Tortillas, especially corn tortillas, can sometimes crack when you try to roll them. To prevent this, simply warm them in the microwave with a damp paper towel for 20 seconds.
