Jumbo slice

[1] Individual slices can measure more than 1 foot (30 cm) in length, weigh approximately 1 pound (0.5 kg), and are typically folded to eat.

[3] Prior to application, sauce is held in a large receptacle sometimes nicknamed a "garbage can", and the mozzarella-provolone cheese mix can arrive in 900-pound (410 kg) shipments.

A single jumbo slice may contain more than 1,000 kilocalories (4200 kJ),[4] as confirmed in a study conducted by ABC Research Corp. on behalf of the Washington City Paper.

[2] Koronet Pizza, located in the Morningside Heights neighborhood in New York City, began selling oversized pie slices upon its opening in 1981.

"[11] The term "jumbo slice" was first used in Adams Morgan by Chris Chishti, owner of Pizza Mart, which has operated in the neighborhood since the 1990s.

[8] As the jumbo slice developed, Chisti upgraded to larger ovens and, once constrained by the maximum size commercially available, even experimented with oval pizzas.

"[2] Chishti responded by going to a larger size, and staked his claim to the term by hanging a plastic sign in his window reading "Jumbo Slice".

[2] Owned by a former business partner of Chishti, John Nasir, and operated by Kerry Guneri, Pizza Boli's installed a neon sign reading "Original Jumbo Slice".

"[2] Other pizza shops in Washington, D.C., have also laid claim to the phrase "jumbo slice", including locations along the intersecting U Street corridor,[12] and near the Catholic University of America in the Brookland neighborhood.
