Ah, Betox! I just thought of Googling the name after having a conversation with an Australian about the relative merits of Marmite and Vegemite. Well, I was brought up on Betox, which was a similar yeast-extract spread, though not as salty as Marmite and easier to spread on soft butter. Mmmmm! The best thing in the world was an end of a crusty loaf, still warm from the oven, with lots of butter and Betox! I was devastated when Betox vanished from the shops and I had to transfer my affections to Marmite. Still miss it though it was decades ago. I suppose you could make a drink from it, like Oxo and Bovril. You could also add it to gravy but it was best on buttered toast or bread - or crumpets. Oh, Yum!
