Omelette can be made in various ways and this is a special omelette. The difference between an ordinary omelet and spanish one is potatoes. In the omelette mixture normally, cooked potatoes are added and then the potato omelet mixture is spread like a pancake and cooked well on both sides. Ordinary omelet does not use any cooked potatoes but the eggs are beaten well with basic dry spices such as salt and pepper and made like an omelet pancake by cooking it well.
