|Coffee berries. They sorta taste like grapes...|
I air-dried them for 3 days, removing the paper husk surrounding the bean. I then roasted them in a cast iron pan (not the ideal method, but I didn't have access to a coffee roaster at the time).
Finally, I ground them and make a cup of coffee. A bit light, very tasty. I don't think it's worth the time investment - I've since gone back to buying gourmet coffee. I might revisit this one day in the future when I have a greenhouse.
