I have replaced most of my aluminum cookware, but I'm having a very difficult time finding good quality, non-aluminum muffin pan, jelly roll pans, and a griddle. We had a Lodge cast iron griddle that we thought was going to be good, but it didn't evenly heat and burned the food I cooked every time. Because of this experience, I'm leery to buy cast iron muffin pans. Is there a good source of stainless steel for these items?
Most of mine is older bakeware that I've picked up secondhand (thrift shops, estate sales - sometimes I even find really nice commercial kitchen type stuff). Not sure if that's a big help, cause it has taken quite some time to accumulate, but you might have better luck looking used than among new products.
I haven't used the muffin pans, but I have other clay bakeware and I wonder whether muffins would actually work out pretty well in those (when well-buttered, I've found them to work pretty well for other similar foodstuff).
