The open flame method is our favorite way to heat tortillas because it produces beautiful tortillas, and the flavor of flame-heated tortillas can’t be beat. For this method, heat your gas flame to medium heat, then place the tortilla directly over the flame for 30 seconds to 1 minute — until the tortilla is browned and begins to fluff up, then flip and heat for an additional 30 seconds. If you don’t have a gas range, don’t worry – you can still get great tortillas with the pan-heated method: place a cast iron pan or comal over medium-high heat and let it heat for 3-5 minutes. Once you’re ready to warm the tortillas, reduce the heat to medium and place one tortilla on the pan. Cook for 30 seconds to 1 minute, until the tortilla is browned and begins to fluff up, then flip and heat for an additional 30 seconds.
