I was pretty much self-taught on cooking. My parents cooked and I watched and learned. They were surprised to discover I had made myself french toast for breakfast one day when my classes started well after they both left for work. I just told them it was no big deal because I'd seen them do it. So I cooked my own breakfast from age 10 or so. I was very good at reading and they had a Betty Crocker cookbook.
But as far as school, I'm older than Title IX: So no Home Ec for me but shop classes out the wazoo.
