In Spain, the humble potato omelet, the tortilla, is revered like a priceless work of art. Round, yellow and resplendent, it is worshiped like a sun god. It is perhaps the most versatile and widely accepted dish in Spanish cuisine. It can be eaten hot or cold, while sitting down at a table or standing at the counter of a bar, in a sandwich on the train or as part of a picnic in the country.
