Great suggestions everyone, thank you! Will do a little more experimenting-- I usually shy away from packaged 'novelties' like the S n' B, but since we had it in the cupboard, figured I'd give it a shot. Tasted pretty darn good overall for being such an ancient box!
We've got a few more packages, so will see about messing around with them some more with my new-found techniques! Definitely could have had the griddle hotter than I did, and that makes a lot of sense about the second side cooking differently than the first!
Ya'll are just a wealth of help!
