Before you have a head flip - this a UK version of the Mexican tortilla. It's not orginial.
Mix the flour and add the water. Mix into a dough and knead for a bit.
Let the dough rest.
Form 50g balls and press in your tortilla press or flatten them with a rolling pin. Fry / bake in a very hot lightly oiled frying pan until brown spots appear on the frying pan side of the tortilla. Turn, fry / bake the other side.
