I taught my wife to cook on cast iron. (well, I taught her to cook, period)
We use cast iron daily, on the stove, on the grill, on fires. We have a 2 burner griddle, 2 8 inch and a 10 inch skillet, a square 8 inch griddle skillet, a few assorted 4 inch thingies, a dutch oven, an aebleskiver pan (viking pancakes) and a muffin pan. We also have a lot of enameled cast iron for various other uses.
tips:
Crisco is good for One Thing and ONLY One Thing in the universe, and that is seasoning pans. I won't buy, well haven't had to buy, preseasoned and wouldn't want to. season with crisco or really GOOD, CLEAR lard if you're superstitious.
I live in an area where the water is so mineralized that I do in fact go to a lab I have access to and use DI water (distilled, for all intents and purposes) after washing, but the key is wash and rinse ridiculously well before seasoning. crisco. you'll love it.
take your seasoning instructions, cut the temp by 50 degrees and double the seasoning time.
cook lots of non goopy stuff (eggs in butter, deep fried stuff, etc for a while to let the seasoning...season.
DON'T OVERHEAT.
oil regularly.
kind of like a good carbon steel knife.
oh, the consumerist brand thing. Don't matter. I have everything from chinese to Lodge to antique WagnerWare and from LeCrueset to Ikea Knockoff. doesn't matter. Doesn't Matter. DOESN'T MATTER. only thing that matters is that it is cast out of something reasonably approaching what a 19th century frontier smelting operation could produce and if it's THICK enough. (and don't assume that the chinese stuff is going to be thinner than walmart-contract-low-end-not-quite-real-Lodge)
