Cenovis is a product based on yeast extract similar to Marmite and Vegemite, rich in vitamin B1. In the form of a dark brown food paste, it is used to flavour soups, sausages, and salads. The most popular way to consume Cenovis is, however, to spread it on a slice of buttered bread. Cenovis is popular in Switzerland, where it was developed in 1931 and is produced today by the company Cenovis SA.
