JR responded with that website, but I couldn't find any specifics on there. Sure would like one of their roasters they have$$$!
Going to have to ask JR about his cast iron skillet method.
Not worried about the smell, closest neighbor is over a mile away...
A hint about hot air popcorn poppers. There are two types, one has a screen at the bottom, one has louvres around the sides and a solid bottom.
The kind with the screen WILL catch on fire if coffee oils build up. I know that from experience. ;)
