We must all be from the same family.
Mom was the kitchen cook, Dad did the BBQ and was pretty handy on the grill. We had a rotisserie so did whole chickens and that sort of thing as well as burgers, steaks, etc. My mother was also a baker, so lots of home-baked pies, cookies, squares, and so on around (I'd be in serious trouble if I had been diabetic back then).
I wouldn't say Sunday was always a roast, but it was something fairly "big". Roast beef, pork loin, roast chicken, slow cooked roast or stew once she got a slow cooker (put it on before leaving for church).
Saturday, OTOH, was basically light, fast stuff because we often had skating lessons or other such activities. Burgers (BBQ in summer, fried in winter), mac & cheese (also creamettes, I think) type of stuff. I make the latter myself a lot but it's more of a lunch dish now (make a large pot, eat some fresh, freeze the rest for future use).
She made her own chocolate fudge syrup.
I remember my mother doing that on occasion. For sundaes mostly.
I have a whole sensory experience of Sundays past involving a walk in the fall air, the smell of the roast beef and turnips
Yep, walking home from a friend's place on Sunday inevitably meant inhaling the delicious fumes of assorted Sunday dinners in the oven.
