This makes an excellent tortilla with fresh broad beans, new potatoes and fresh mint. You can vary the ingredients of the potato tortilla according to the season, a spring tortilla is good with purple sprouting broccoli. I have to admit I cheat when I make a tortilla, many years ago I used to turn them over the traditional way but after many near disasters I started to use the cheats method by placing the tortilla under the grill but by all means try turning it if you wish.
