Ok, so it's been about 3 weeks since I first posted the question. Since then I've used it several times, on both sides... burgers, brats, eggs, bacon... and everything has been coming out great!
Also made pancakes on it last week a couple of times, and they came out nicely as well. And this morning, made the pancake-bacon dippers. They came out GREAT!!! Shared with a couple of co-workers and met with hearty approval. :)
I may get nominated to make more, LOL.
Skilletlicker, I have been using vegetable oil, and just a thin coat. Just poured a bit on the griddle while warm, and used a paper towel to spread it around, left the burners on low for about 20 minutes. Repeated that after every time I cooked with it, after cleaning it with hot water and a stiff plastic scrub brush to get chunks off. Made sure I let it cool to where it wasn't too hot to avoid warping with a big temperature difference between the water and the heat of the griddle.
Also thought about the electric options that a couple of you have mentioned, but I was determined to get this right
Thanks for everyone's tips and suggestions!!
