Place 1/3 cup of green coffee beans into the hot air popper. Put top back on and turn on/plug in hot air popper. Depending on preference of roast, and whether its a bean that is best dark or medium roasted, roast from 6-9 min. If it gets really dark, almost black, it will start smoking. The beans will be glossy from the oils in the bean. Some people really enjoy coffee with the dark roast. Otherwise, you want it at least the color of milk chocolate and the chaff (skins of the bean have “cracked” and come off the bean) will be evident. With the popper going, a lot of the chaff will end up on your garage floor. I’ve gotten to the point, where I know that 8 min. is just the right time for me. I set my timer and leave the garage for that time. The first time I did this in my house, I set off all the alarms and it wasn’t that smoky. So I do this in the garage now. I have the metal colander handy and dump the beans in there when time is up. I always do a second batch. I then put them into a canning jar with the lid off for several hours, to let the carbon monoxide escape, and the flavor deepen. Then put the lid on and enjoy!
