Just to mention about the flour etc. Back in 1960s Yorkshire, most people had a traditional pudding after noon dinner or tea (meal after 5pm). Add to that pie, cobbler, dumpling, cake and biscuit making, and you'd go through a lot of flour and butter every week.
People ate very differently back then. Main meal portions were far smaller, and there was virtually no pasta or rice served. It pretty much was meat, two veg and potatoes.
When I think back, there really wasn't a lot of calories in a main meal unless you had a pastry dish. My old school dinners must have only had about 200 calories in them without the pudding.
No wonder everyone looked like a rake. 😂
