I have nine pizza cookbooks, and seven of them have a recipe for Pizza Margherita. In part this is because it is a classic, and in part because the story of its creation is clearly known and iconic. In 1889, the Italian royal couple King Umberto and Queen Margherita paid a visit to Naples. While there, local pizzaiolo Raffaele Esposito made three types of pizza for them: a marinara pizza with anchovies; a bianca (white) pizza with lard, provolone or caciocavallo cheese, and basil; and a pizza with tomatoes, mozzarella, and basil, featuring the red, white, and green of the Italian flag. The queen was particularly delighted by that last one, and when Esposito received a note of thanks from her, he dedicated the pizza to her.
