Restoring my first cast iron, but it doesn't fit inside of my toaster oven (help)
The handle annoyingly sticks out a few cm outside of my oven so it can't close entirely. I've read a post somewhere of someone with the same problem and they said that they covered the open part with tinfoil and did the usual seasoning steps and it worked, but that doesn't really sound foolproof to me. The alternative is seasoning it on my gas stovetop but apparently it's not good because of uneven heating from the fire, BUT I have this metal plate designed to heat stuff evenly (2nd picture). Can I use that? But I'm afraid it won't get hot enough. Please give suggestions (sorry if some of that didn't make sense English isn't my 1st language)
edit: I'm gonna clean the rust and gunk off the pan before seasoning it of course!! forgot to mention it in the post, sorry for the confusion!
