LOVE a blackstone!
brother-in-law bought the 17" last year and took it camping with us. i was impressed and got one and love it. i also bought the 22" for the back patio at the house and bought the pizza oven attachment for it. that was a great purchase because it will get up to over 900 degrees and make pizzas as good as the wood fired ovens do.
i took a perforated pizza pan and put it on the 17" grill and placed a few small pieces of broken tile between the grill and pan to give an air gap and with the lid closed, it also makes a great pizza. it is an awesome grill!
i did adapt the 17" grill with a hose so i can use my 11# propane tank and went with a big heavy spatula to do smash burgers. we just used the 17" in north goergia last month...nice cool mountain morning with bacon, eggs and hashbrowns on the grill...insanely good!
there are so many good recipes on youtube for the blackstone (well really any flat top grill)
excited for you! its definitely a game changer
