The use of olive oil in this dish connects back to Spain’s Mediterranean climate and advanced harvesting technology, which is ideal for olive farming. Additionally, Spain’s agricultural history makes it the perfect place to farm eggs and vegetables such as potatoes and onions. Although potatoes and onions are not originally from Spain, the Spanish cultural exchanges with South American and Asian cultures introduced the hearty vegetables to Spain, and the Spanish climate has grown them ever since! The Spanish tortilla is also a great example of Spanish culture, as the simple and nourishing ingredients echo the Spanish relaxed and healthy lifestyle!
