Edinburgh farmers' market, Castle Terrace. 9 - 2 on Saturday. Come and get a bag of Bovril crisps served hot at The Crisp Hut. Can also offer with extra mustard, chili, italian cheese, garlic salt (best seller!) cajun spice or a dozen other flavours as well if you want.
See you there, and dress to impress please.
And I'm sure you are aware they make Bovril as a vegetarian spread - no cow in it unless you buy the drink powder (like what I use). The pastes are a yeast based thing to get a flavour. Practically the same as marmite then. . .
