Despite the fact that 90% of what I ate was home cooked, mostly from scratch, meals, I managed to miss out on some basics like courgette (zucchini) and aubergine (eggplant) and BUTTER if you can believe it.
My mother was big on margarine. So when I moved out I continued the tradition until one day I made a fateful mistake. It was like in Ratatouille. I was sat in my studio just eating buttered bread having an out of body experience.
I was raised to know spinach as the awful canned stuff. Thought I hated spinach for years. Found out in my twenties I love it when its not garbage from a can.
