Step 3

When hot add in the potato slices and onion slices.

Step 4

Sprinkle with a good bit of salt and a pepper,

Step 5

Using a wooden spoon gently turn the mixture in oil and adjust the heat so the oil is just bubbly but not too hot.

Add in two tablespoons of the reserved oil and heat to a medium flame.

Step 11

Add this to the heated oil.

Step 13

As soon as the edges start to firm, reduce the heat to medium-low. Cook for 5 minutes.

Step 14

Using a rubber spatula run it along the edges of the tortilla.

Step 15

Step 17

Add another tablespoon of oil to the skillet and slide the tortilla back into the skillet.

Step 18

Cook another 5 minutes and then slide onto a clean plate.
