Peperami is a pork sausage snack manufactured by Unilever in Germany, Mexico and Britain. According to Unilever, it was first shipped to the UK by accident in a container which was supposed to be carrying pâté. The company decided to attempt to sell the shipment to the UK market under the brand name ‘Peperami’. Several new varieties have been introduced over the years with varying degrees of success. Peperami may be interpreted as a portmanteau of the words “pepperoni” and “salami”, but the company does not want the product to be misunderstood as a combination of these different meats. In the year 1955, Peperami was one of the products from Nabisco. When the mistake was made, the company tried the meat snack and enjoyed it. Thus, Unilever relaunched the snack.
