I love food threads thanks OP!
in Downton abbey the staff seem to have porridge plus toast and marmalade which is now pretty much my daily breakfast. The upstairs lot have scrambled eggs, bacon and toast. (I know it is a tv series, but this is the sort of thing I look out for!).
My mother (now aged 75) was brought up outside the UK in a very rural area. They used to have mince and peas on toast, porridge with milk and butter; scones etc. They had meat of some sort 3 times a day. Usually lamb chops for lunch etc. They were all - very well upholstered. She desribes her upbringing as extremely poor but there were 4 kids and meat 3 times a day which to me seems amazing.
Father aged 75 same rural area as my mother used to have toast, butter and jam and porridge
DH was brought up in the UK and the 60s and in a well off family who had a full time cook. They would have kedgeree, scrambled eggs, toast, fruit salads, muesli, kippers and also trout which he would fish for in the morning.
Me brought up in a different country and in the 70s it was usually toast with butter and honey. Maybe some grapefuit. Scrambled eggs at the weekends.
