This is a cooking video from someone who has spent a lot of time trying to learn how to make "New York style pizza" at home. I have the feeling this guy has learned how to do that about as well as it can be done…but I also have the reaction that it is clearly more trouble than it is worth. And unless you value your time as being close to worthless, it's not even a way to save money.
I find myself watching a lot of cooking videos these days and as a result, I have just about given up cooking myself. I was never very good at it and about 35% of the time, the end product was such a total disaster that a few bites into it, it went right into the garbage. I'm not a good cook and while I would enjoy the satisfaction of doing it myself, a better course of action for me would be to let some professional make my meal and for me to spend the time 'n' effort on something that will give me more satisfaction because I stand a better chance of having it turn out well.
