My mother never made bread and butter pudding - my father had a serious aversion to milk and cream, so he'd never eat anything that even looked as if it had milk in it. For years my poor mother had to pretend there was no milk in Yorkshire pudding (which he loved) - there'd be a hissed, 'Get Daddy out of the kitchen!' so she could assemble it on the quiet.,
So TBH I always thought B&B pud sounded gross! However having had it at a friend's house ages ago, and found it delish, I do make it now and then, though we usually have puds only when we've got guests, otherwise we'd both be like the side of a house.
