As much as the internet is helpful, I am finding SO much mixed information regarding seasoning cast iron. I had a set of cast iron pans from my grandmother, and I'd lent them to my sister. I just dug them out of where they were packed, hoping to make some cornbread in them and THE SEASONING IS GONE!!!! Perfectly seasoned cast iron cookware lovingly cared for over the years is now ruined. Now I have to start from square one. I've never done that before, only done maintenance seasoning, i.e. wiping with oil and then heat 'til smoke on the stovetop. Can I use coconut oil on it? I only have that and olive oil on hand. I tend to use the food quality coconut oil in soap making, but it seems like it would work well with seasoning. I know I'll have to probably put on several layers and bake the cookware in the oven for each layer to build the seasoning back up again.
