If you are serious about cooking Cajun or Creole Food, you need some serious cookware. Serious doesn't mean expensive necessarily, I mean well made cast iron is what I recommend for your cooking. Lodge, I understand, is the only American made cast iron you can buy now. I own their 7 qt. Dutch Oven and it is marvelous. Nothing makes a roux like cast iron.
I use it for everything I cook nearly, gumbos, jambalayas, red beans, etouffée, and it's great for deep frying. Lodge skillets and kettles come pre-seasoned and are ready to go, right out of the box. The have factory outlet stores here and there, I found the best bargain, if you'd like the dutch oven, is buy it on-line from Walmart, pick it up at the store and pay no shipping.
Their chicken fryer is a great product as well. It's like an extra deep skillet with a lid. They still make corn bread molds and all sorts of skillets and griddles. This cast iron will last you a lifetime and can be passed on to your children or other family when you kick off.
