My dad's mum was a pretty poor cook, but my mum learned a lot of things from her mum, AND when she was a girl household skills were taught. The cotton mill where she started work in Bolton owned a house, and the girls had two half days a week there, learning cookery in the morning session and cleaning, ironing etc in their afternoon one.
Since her father died when she was only 8, money was tight, so wholesome dishes made from cheaper ingredients were the order of the day, and my mum can still rustle them up at the drop of a hat (plus a couple of hours developing flavour in the oven).
One such is "sea pie", the main ingredients of which are dried peas (after soaking), minced beef and an onion, cooked in a deep dish with a suet crust. I don't know whether the name derives from being served aboard ships or from the green colour.
Her mum usually made her own bread, and excellent pastry, though her cakes were said to be awful!
With money tight, it was the children who were sent to do the shopping, as they would not be tempted by expensive "treats". Does anyone else use the expression "half a dozen of flour", meaning six pounds weight?
With their only parent at work when they finished school, my mum and her sister would be pestered by their school friends who wanted to "play house" - so the chores were often done well before my grandma returned home!
The great baker on my dad's side was my great aunt Eunice, who was a trained confectioner. No matter what the job we did for her, full payment was AN APPLE PIE.
