I wanted to add a griddle to my pellet grill so I thought I would just buy a Lodge and be done with it. I was intrigued by the positive reviews of the Blackstone and I ended up buying the 17” tabletop model thinking it might come in handy if I ever went camping (haven’t been camping in 20 years LOL). I seasoned the griddle and decided to cook smash burgers. I used a camping size bottle of propane and preheated the griddle, threw the burgers on and ended up with a disaster. The griddle never got hotter than 250 degrees and the burgers weren’t cooking ver well so I ended up taking the griddle top and placing it on my pellet grill. My question is was I expecting too much out of this Blackstone? Would a standard propane cylinder produce higher heat?
