Food blogging introduced us to Spanish fried eggs. All credit goes to In Praise of Sardines, where this method of huevos fritos captured our attention. We’ve haven’t fried an egg any other way since. What’s a Spanish fried egg? It’s an egg fried very quickly in very, very hot olive oil. Some use olive oil AND butter but just olive oil does fine. What you get in a Spanish fried egg is a crispy, delicate white that crunches then practically melts in your mouth.
