Roasting Coffee in a Popcorn Pumper
So I roasted my own coffee on the weekend, using my old Popcorn Pumper air popper, and using the instructions I found on Sweet Maria's.
The bit at the end with me swirling the beans in a metal collander is the cooling process for the beans. It comes after the "before and after pictures" because it was from the second batch I roasted...
I used green beans from JJ Bean, a Proctor Silex Popcorn Pumper, a metal collander, and a glass jar to store the roasted beans. I found that a batch took me around 8 or 9 minutes.
