Spam 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.
