My new favourite hobby is roasting my own coffee. Delicious and awesome.
I started off by researching easy ways to roast coffee at home and came upon this video:
I found a cheap (free actually) popper at a yard sale.
I ordered the green coffee beans from Sweet Maria's (the company that also made the video). It cost me (after shipping) just shy of 30 dollars for 4 different varieties of coffee (one pound each).
Following the instructions in the video, each roasting session lasts about 5 to 7 minutes. I roast the coffee the day before and then enjoy the freshly roasted coffee the next day. I have just been amazed with the results.
