Tortilla Espanola

Tortilla Espanola (Spanish omelette) is the quintessential everyday dish of Spain, made from just three ingredients: eggs, potatoes, and olive oil, yet achieving something far greater than the sum of its parts. The key is the slow-cooking of the potato slices in abundant olive oil before combining with beaten eggs, then flipping the whole tortilla with a confident wrist motion. Eternal debate rages about whether to include onion (con cebolla) or not (sin cebolla), a division as serious as any political rivalry.
