What sold me on the cast irons was one Thanksgiving, I was going to make a green bean casserole using fresh ingredients, nothing canned except the Durkee onions for a topping.
I started off with two cast irons (big dinner) and equally divided up chopped bacon, mushrooms, garlic, etc. When i finished sauteing, I decided "why dirty a clean casserole dish?" and I proceeded to finish the casseroles in the skillets. The flavor was tremendous and serving it in a cast iron looked extra country and homey. They work well on stove top and in the oven.
I've been sold on cast irons ever since and hope to get my first cast iron dutch oven for Christmas. (with NO enamel TYVM). :)
Corn bread is another cast iron treat..... YUM...
Sorry, I got carried away about cast irons... <3
