I purchased some green coffee beans to take a stab at home roasting. I have done a lot of research and decided to try using the wok on the egg. I was pleasantly surprised with my first attempt. There is a little bit of a mess with some chaff and a little smoke so it was a logical place to try. I find it hard to control the temp of the wok with the lid up but overall it was a fun experience that I will try again. I grind my own beans and use a french press and make a darn good cup of coffee.
