Just got done making this over a wood fire. The only thing missing was more cinnamon. Made it in a cast iron skillet. Will definitely make again.
It was pretty good but I suggest cooking an apple pie on the grill instead of the crisp.
I thought the recipe was good. I would add more spice next time and it wasn't quite as "juicy" as normal apple crisps in the oven. Not sure I'll try it again though...
