Mistakes, I've made a few
Knowing what you know now, what would you do differently as regards cookware? In my case I might have purchased a carbon steel pan instead of my Staub fry pan. Instead of a 2 quart saucier and 4 quart AC Essential pan I would buy a 3 quart saucier. And why did I buy 3 roasting pans? What was I thinking? Oh, and that wok. Oy.
I have run through a good number of pans - can't really say I regret any although I have finally upgraded to a point where I am pretty happy with my batterie - (I would like one or two nice copper pieces added) I do need to focus on weeding out the unused items that hog space
I do have a set of VitaCraft "waterless" cookware that I just could not resist they were so cheap - and they are pretty nicely made SS/AL/SS with the lids that spin around and double as trivets LOL - and they stack nicely - but I really have NO USE FOR THEM If I could only communicate to my housemate how perfect they are for his type of cooking (reheating and boiling) he may keep his hands off of my CI and Anodized. If I could go put it back on the shelf and walk away I would
Most of the "regrets" I have are more in the small appliance category
Blender/food processor that did neither well and had a gazillion breakable/losable parts - now happy with a basic blender and a real food processor
Rice cookers # 1 and # 2 (just not the place to go cheap and small) # 3 a Breville is perfect
The biggest "dislike" is my slow cooker or "multicooker" - it was a very thoughtful and expensive gift - but I hate the Teflon coating because I am always afraid of scratching it -also It is supposed to do all this additional stuff like browning and steaming - but those features don't work and by the time I realized it was a common product defect and not my not understanding how to use it it was too late to return it
also while it is very nicely styled brushed SS look I find the outside hard to clean and I cracked the plastic around the controls - for something that was pretty pricy it is sort of cheaply made
that said I use it constantly but I will chose differently when the time comes to replace it.
My Vollrath Tribute 2 qt saucier, while very well made, is too shallow. I should have sprung for a 3 qt Demeyere or Mauviel instead.
6 qt. Vollrath Optio saute pan. It's huge. To be fair, the disk began to separate a bit from the pan, but it was still usable. I just don't need it.
Cheap carbon steel stir fry pan - the base is too big for everything but popcorn. And it warped the first time I used it.
That cast iron DO from Costco? I have no explanation.
While DW is a self-proclaimed non-cook, she enjoys baking from time to time and is really pretty good at it.
In her wedding registry she asked for and received a popover pan. In the 14 years that we've been married, the only time that pan is been out of the cupboard is when we've had to move it to get to something else. And every time it comes out, she looks at it and says, "I've got to make a batch of popovers one of these days." And then it goes back into the cupboard. And so it goes.
