Phil's pretty well summed it up.
Sets are initially appealing. But far too often they contain pieces that you never use. So the value just isn't there.
Unfortunately, it's often the case that a particular item you want is not available in open stock, and only comes as part of a set. Poor marketing on the maker's part, IMO.
There is nothing wrong with glass lids. They're made of tempered glass, and can withstand a pretty wide shift in temperatures. But I don't know why you'd want to drop a hot one into cold water. That's not really a good idea for any cookware material.
As to All-Clad, I'm one of those who have no use for the company, which has the worst customer service in the industry. You couldn't give me another piece of All-Clad, let alone sell me one of the over-priced things.
I've had good luck with Calphalon. Also Henkels and others at that level. But, by the same token, my Wear-Ever pots have lasted a long time, with no problems. What I'm saying is that you don't have to invest the equivalent of a second mortgage in cookware.
Also, don't forget there are many materials in addition to stainless. Check out, for instance, some of the carbon steel pots and pans, which are just as good and usually a lot cheaper.
Cast iron---either coated or not---has uses that cannot be duplicated with other materails, and you might look into at least one iron skillet and "Dutch oven."
And, despite the potential health issues (for most of which the jury is still out), you'll find that most commercial kitchen are loaded with aluminum pots and pans.  |
