Cod liver oil is foul. I was made to take it as a child, an couldn,t stand it.
Had a long discussion with my brother tonight in the pub. He lives in Burton-on-Trent where marmite is made, and says that the lorries are constantly to-ing and fro-ing all day, collecting the spent yeast from all the breweries there.
Funny thing, though, bovril and oxo cubes are also made there, and not a cow in sight!!!! Hwyl, Bron.
