OK, I am getting some new cast iron cookware today from Lodge.
I really didn't like the result I got from veg. oil, it was always sticky on the outside.
The only argument I heard against lard is that it may turn rancid, but if you use it often, it should be OK?
I always have a problem with the bottom of the cast iron ware rusting though, I think most people seaon only the inside but the outside get dry from flames and heat.
