About 8 or 9 years old. I remember taking out books from the library to cook granola and sweet cookie-type stuff that kids would like, and then I remember learning how to make omelets by the time I was about 10 or so. Oddly enough, I almost never make omelets these days.
If you count breakfast, about 10, with the omelet. I also learned pancakes (from a mix) and scrambled eggs at about the same time.
Same as above. None dead. I used to make my mom omelets for breakfast occasionally.
Now, cooking breakfast and the occasional dessert was pretty much all I knew how to do until college. I didn’t start on soups, stir-fries, roasts, or anything like that until I lived in my own place. And I don’t feel I really started understanding how to cook well until after I graduated college and lived on my own. My roommates remember me as a good cook my junior and senior year of college, but, looking back at those days, I don’t really feel like I knew what I was doing. I was still having fun and experimenting and learning, but not quite understanding how all the pieces fit together.
Depends by what “complex” means. Is classic chocolate mousse from scratch (whipped egg whites and all) “complex”? If so, then about 14 or 15.
I can’t think of a specific dish. I can think of breakthroughs in terms of philosophy, though. In 1996 I took the better part of a year off from my university studies and worked and volunteered in Europe. The first two months I worked at a Michelin starred restaurant as a kitchen porter in Scotland. This was the first time I had ever encountered fine cuisine. I learned how to identify, name, and use all sorts of herbs I hadn’t seen or used before, or only vaguely knew in dried form, but had never seen in real life. I learned the importance of fresh ingredients. And I learned cooking actually wasn’t all that (or needn’t be) complicated. That to make a great meal, you don’t need a recipe with “secret” ingredients and a laundry list of herbs and spices or whatnot. Just use good ingredients and good technique to build and complement flavors.
And, at the risk of over-romanticizing that time of my life, I also had a revelation later that year at a hotel breakfast in Paris. It was just a simple continental breakfast, but that simple baguette and butter is the breakfast that I will most remember in my life. I literally had no idea how good a baguette and butter could taste. And that reinforced my lesson of it doesn’t have to be complicated to be good.
Then, living in Hungary for 5-ish years, I further learned the importance of shopping in season, and how you can build great dishes out of very simple ingredients, and when to pay premiums for certain ingredients, and when not to.
On my own. I mean, I would watch my father and mother cook growing up, but when I was learning, my mistakes and triumphs were my own.
