Marmite and Vegemite

Marmite and Vegemite are two brands of spreadable sticky paste that is popular in Great Britain, Australia, and New Zealand. I use this spread as a substitute for beef extract when I am working with textured vegetable protein (TVP). Marmite is also a good source of vitamin B12. A beef-flavored vegan boullion cube can also be used to attain the same effect.
