Pizza is a savory dish of Italian origin, consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients (anchovies, olives, meat, etc.) baked at a high temperature, traditionally in a wood-fired oven. A small pizza is sometimes called a pizzetta. In Italy, pizza served in formal settings, such as at a restaurant, is presented unsliced and eaten with the use of a knife and fork. In casual settings it is cut into wedges to be eaten while held in the hand. The term pizza was first recorded in the 10th century in a Latin manuscript from the Southern Italian town of Gaeta in Lazio, on the border with Campania. It has become one of the most popular foods in the world and a common fast food item in Europe and North America, available at pizzerias (restaurants specializing in pizza), restaurants offering Mediterranean cuisine, and via pizza delivery. Many companies sell ready-baked frozen pizzas to be reheated in an ordinary home oven. The Associazione Verace Pizza Napoletana (lit. True Neapolitan Pizza Association) is a non-profit organization founded in 1984 with headquarters in Naples that aims to promote traditional Neapolitan pizza. In 2009, upon Italy's request, Neapolitan pizza was registered with the European Union as a Traditional Speciality Guaranteed dish, and in 2017 the art of its making was included on UNESCO's list of intangible cultural heritage.

Rocky road ice cream is a chocolate flavored ice cream. Though there are variations from the original flavor, it is traditionally composed of chocolate ice cream, nuts, and whole or diced marshmallows. According to one source, the flavor was created in March 1929 by William Dreyer in Oakland, California when he cut up walnuts and marshmallows with his wife's sewing scissors and added them to his chocolate ice cream in a manner that reflected how his partner Joseph Edy's chocolate candy creation incorporated walnuts and marshmallow pieces. Alternatively, Fentons Creamery in Oakland claims that William Dreyer based his recipe on a Rocky Road-style ice cream flavor invented by his friend, Fentons' George Farren, who blended his own Rocky Road-style candy bar into ice cream; however, Dreyer substituted almonds for walnuts. The original Rocky Road ice cream used chocolate ice cream with no chocolate chip pieces. By blending numerous ingredients such as chocolate ice cream, nuts, and marshmallows, the rocky road flavor was one of the first types to mix in the materials together. This was only made possible by the revolutionary powers of refrigeration. This style was developed by Dreyer's lead chemical engineer and dairy chef Noah Holladay and proved difficult to produce due to the nature of freezing and preserving various mixed ingredients. Over the years after the inception on the flavor, many companies would try to imitate or mix in other ingredients such as various nuts, fruits, and toppings, but the original combination proved to be the most popular.
