Italian aristocrats of the nineteenth century didn’t eat pizza. It was peasant food, flavoured with that peasant favourite: garlic. However, in the 1880s, European royalty, wary of revolution, were all trying to be nice to the common men whom they ruled. So when King Umberto and Queen Margherita visited Naples, the home of the pizza, a man named Raffaele Esposito decided to make a pizza fit for the lips of the queen.
Esposito was the owner of the Pizzeria di Pietro e Basta Così, and he got over the garlic problem by simply not using any garlic, an idea that was previously unheard of. He then decided to make the pizza properly patriotic and Italian by modelling it on the colours of the flag: red, white and green. So he added tomatoes for the red (nobody had done this before), mozzarella for the white, and herbs for the green.
