The game's up then, carbon! We always had sterilised milk in our two up two down working class household (I suspect because it had better keeping qualities than pasteurised and we did not own a 'fridge). However, sterilised milk in tea is the reason that I cannot now take milk of any form in tea. It is truly disgusting. In the early sixties, in our neck of the northern woods, women often wore curlers in their hair, covered by a headscarf. I always thought this looked extremely common, but as my two older sisters often did it, I could not voice an opinion lest I get a clip around the ear! I think that must have been the sixties equivalent of going out in one's pyjamas!
