Pour a thin layer of coffee beans about ¼ – ½ inch thick in a cast iron skillet
Place chunks of alder (or a smoking wood of your choice) on the charcoal to create a nice billowing smoke
Remove the beans from the grill & pour them into a bowl or aluminum pan quickly or they will keep roasting & potentially burn.
After they cool completely, place them in a sealed container for at least 24 hrs to give the flavor time to intensify. Grind & make coffee as you normally would!
