Patatas bravas literally means «fierce potatoes» in Spanish, referring to the bite of the spicy sauce that tops them. The dish originated in Madrid in the mid-20th century and quickly spread through Spanish tapas bars, becoming one of the most-ordered dishes at any traditional Spanish bar.

The dish relies on a simple but precise principle: frying potato cubes twice to achieve a very crispy exterior while keeping the inside fluffy, then topping them with two contrasting sauces — a sharp, spicy tomato sauce, and a cold, creamy garlic aioli or mayonnaise. The contrast between hot and cold, sharp and creamy, creates a well-rounded flavour experience.
