I think that the routine meals were affected by other things. In the days before automatic washing machines, wash day was more or less that. I remember us having a washing machine with a mangle on the top of it, but my mother still had to put things through the wringer , which was quite tough work especially bedding etc. She had an electric iron, but no steam one in those days, and she baked and made just about everything from scratch. So part of the menu was to fit in with the work and looking after 2 little girls at the time, and we came home for lunch from school too.
That meant that the sunday lunch was a roast that then provided cold meat to be eaten with baked potatoes and salad, or bubble and squeak in the winter. She would have been working hard sorting the washing out and needed to have a meal that could be made quickly . Middle of the week sort of meals could be liver and kidney done with onions and mushrooms with lovely gravy with it, and we also often had fish on fridays , despite the fact that we were not catholic. But of course the fishmonger had a good choice for those who were and so we also then had more choice so we would also have lovely fresh fish, and range from straightforward fish and chips to kedgeree (which I loved!) made with brown rice and hardboiled eggs, or some smoked haddock. Saturdays were a day for simple things as we would be doing a lot of things so it was quick and easy to prepare and sometimes when we were doing different things it would have to be either a stew prepared beforehand and just reheated or egg and bacon sort of thing. No microwave, or airfryer available then .So with no fridge but a proper pantry with a cold slab to put the milk and butter etc on, it was a matter of not being rigid about meals or how the day would go but you had got to get through these things with no help and that meant that patterns of meals helped you.
Later with the mod cons available my mother went on to cook whatever she felt like and it was usually very good . I loathed white sauce and even more horrible parsley sauce, but that was the only meal I didnt enjoy. Even today I really find it amazing when I see frozen bubble and squeak or bread and butter pudding, as to me they were dishes that were to use up food in a practical way and waste not want not, and I think we are lucky to have a great range of food available to us now.
