My parents gave supper parties and served lasagne. My father went to Italy on business quite regularly so he brought the sheets back with him. They had to be boiled before the lasagne was assembled.
We lived on a cul de sac and all the Mums stayed at home except one. They were also the only family with a freezer. During the bread strike they defrosted their frozen loaves on the roof of the car on the drive. I think we must have hot one shortly afterwards because DM started serving baby onions in white sauce a lot which came frozen.
I remember lots of mince, sausages, etc. We didn't have chicken as my DF didn't like poultry. Children had a high tea then milk and a biscuit before bed, my parents ate dinner (chops, steaks etc) later together at the table, or even on their laps on trays if there was something they wanted to watch on tv.
On Friday nights after swimming lessons we would stop at the only Chinese takeaway for miles on the way home. DM would have chicken Maryland which came with a fried banana.
I remember the first time I tasted mascarpone it reminded me of tinned UHT cream. I also remember tinned potato salad and vegetable salad.
We always took the skin off potatoes. Was that a 70s thing? Peeling old potatoes but literally scraping the flaky skin off jersey royals so they were bare before cooking. It seems so weird now. Except Jacket Potatoes of course, which we ate on bonfire night.
