I took Gordon Ramsay's MasterClass on cooking and it helped me in some small but surprisingly useful ways. The knife skills part helped me be safer and faster in the kitchen, for example. It was also a good refresher on certain ingredients. In some ways, I learned more basic and fewer skills than I expected, and there was some random stuff in there that you won't really need unless you plan on opening a restaurant. Yet, at the same time, it was refreshing to have a high quality, practical course that I could pause, rewind, and re-watch until I had mastered all of the little details. My cooking has definitely improved because of it and it was worth the cost.
