Instructions
Step 1: Heat the Pan and Melt the Butter
Place a large skillet or griddle over medium heat. Once the pan is warm, add the butter and let it melt, swirling the pan to coat the bottom evenly. Wait until the butter stops foaming and the pan is properly heated before adding the tortilla — a properly heated pan is the difference between a pale, soft quesadilla and one with a beautiful golden-brown crust.
Step 2: Lay Down the First Tortilla
Place one flour tortilla flat in the buttered skillet. Let it sit for about 30 seconds so the bottom side begins to warm and absorb a little of the butter.
