Sure! Would be even better if you started with green coffee and did the three steps of Roast, Grind, Brew. A lot easier than you think.
For roasting you can use this over an open fire, Amazon.com: Customer reviews: Gene Cafe Handheld Pan Coffee Roaster (CBR-P01) for Home and Outdoor Use
Then use a Hario hand grinder, COFFEE/GRINDER/Ceramic Coffee Mill – HARIO Co., Ltd.group=MSCS-2TB
And finally have your friend brew like he normally does since he already has experience with his method.
Good luck! Let me know how it turns out!
