Spam (shortened from spiced ham) is a canned precooked meat product made by the Hormel Foods Corporation, first introduced in 1937. The labeled ingredients in the classic variety of Spam are chopped pork shoulder meat, with ham meat added, salt, water, modified potato starch as a binder, and sodium nitrite as a preservative. Spam's gelatinous glaze, or aspic, forms from the cooling of meat stock.
The product has become part of many jokes and urban legends about mystery meat, which has made it part of pop culture and folklore. Through a Monty Python sketch, in which Spam is portrayed as ubiquitous and inescapable, its name has come to be given to electronic spam, especially spam email.
