Tuesay January 17 is the International Day of Italian Pizza — a celebration of the 10th International Day of Italian Cuisines (IDIC).

It celebrates the Italian-born Margherita Pizza, made with tomato, mozzarella, basil, and olive oil, as well as the Signature Pizza, where the dough is made in accordance with Italian standards while the chef chooses the toppings.

"Pizza is the Trojan horse that opens all the doors to the Italian chefs, to the restaurants and to the culinary Italy, in the world,” said Mario Caramella, president of the Forum GVCI (Virtual Group of Italian Chefs).

"It’s also the most counterfeited dish," he added.
