Notes
The cook time is for one tortilla wrap. Cooking a larger amount will increase the cooking time, unless you have multiple pans heating simultaneously.
You need to use a really heavy based pan for this recipe.
The pan needs to be very very hot for these to cook. Heat your pan for a good 4 minutes before you add a tortilla to it. This will help it to puff up and give it those bubbles.
If you have a gas stove and want to give it a proper charred look, then hold each side of the tortilla over a flame for 30 seconds.
