True, but I also think that the cast iron pan *is* a simple solution, with the advantage that the cast iron has enough thermal inertia to make steam.
Also, for most ovens you do not want a lightweight sheet on the bottom of the oven.
And no, not a commercial kitchen by any stretch. Since I am going to make a mess one way or another, I might as well get 4-8 loaves of bread out of it and clean up just once. That produces enough bread for us for a few days and a couple or so more to give to the neighbors. It's not something I do all the time, it's when I'm in the mood to bake bread. It happens often enough that I don't mind investing in the equipment, but I'm not saying everyone has to do it.
I'm just saying people have a right to know it can be done if it's what they want.
The other side of "simple problems often have simple solutions" is that many people only use a mixer to whip cream, maybe make a cake from a boxed mix every once in a while and, for most people, a simple, inexpensive hand mixer is just fine, but they use a food processor for lots of other things, so it's already there. There are probably more kitchens today with just one food processor, a hand mixer and an immersion blender than what used to be common, which was one countertop blender, a stand mixer with lots of attachments and no food processor.
Either way, we home cooks have a strong incentive to find out ways to cook with equipment/workflows that is available to the average home, just as professional cooks have a very strong incentive to stick to the methods/workflows they were taught in school so as to maintain a consistent product and work environment as well as produce safe food.
What I object to is one side saying the other side is stupid and/or wrong. And I also strongly dislike when ordinary people automatically assume that only the pros have the answers.
That kind of mindset only tends to produce results like some friends of mine who insisted that the only way to make some of the foods was this hard process that such and such a TV personality showed, then finally I go to the kitchen, make it work for a fraction of the time and effort and they lose faith in the pros completely, which was also not my objective. What I do in the kitchen is optimized for home kitchens, in fact if you double the recipe it might fail and be hard to scale up or down -- what people frequently fail to accept is that commercial/industrial methods are optimized to be scaled up/down and to consistently keep the food safe from spoiling, for example.
One of the best examples of where home and commercial/industrial methods clash spectacularly is canning. We've seen it even here, over and over again. All of the official food canning guidelines encompass everything they've learned in over 100 years of experience with stuff that works and/or can go wrong, so, of course, their recommendations reflect all of that. Meanwhile, there'll be no shortage of people who'll say that their families have been canning without a pressure cooker and just boiling or putting the jars in the oven and inverting them when taking them out etc and "no one ever got sick". Or worse, that their method was the official recommendation back 75 years ago. Yes, it's true that small carefully made batches might be sufficiently safe, but that fails to take into account that millions of people replicating the old methods in not quite the right ways might get food to spoil, or make the glass jar explode and hurt people nearby.
Anyway, sorry if it feels like I'm jumping on your throat in particular or even in general. This has not been the best year for a variety of reasons, and I think that stuff that I ordinarily just let go/pass by are pressing my buttons way more heavily and I feel like I *have* to respond when it's probably best to ignore it. One of those buttons is when people who went to expensive training to be chefs tell me I can't do stuff that has worked consistently in my family for generations. I always go "WTF? If *I* can do it and I have no formal training, shouldn't they also be able to do it?" and then you get my rants. Sorry.
And Happy New Year everyone, here's hoping it's better than 2016!
Hugs all,
