Yeah it is the high heat, less time, that is key. I do a lot of cast iron cooking .. and using ghee or etc that won't smoke (as much) at a high temp. But yes, indoors is pretty smokey. Haha. I should prob get my grill online. Regardless, gotta heat and deal w the smoke or it isn't right.

I do use a lid to tame the smoke for inside, but it is mostly a placebo.
