Sorry I was being a jerk and expressing my bread snobbery to supermarkets who jumped on the sourdough bandwagon! Either way it's a shite thing to do. The amount of times we go somewhere and ask if something is vegan, be told it is, and then find butter or some non-vegan sauce slathered all over it!
not sourdough if it has milk - that's a abomonation. Should only contain flour, salt and water.
