We have a wonderful coffee machine here at the Lodge and like to get creative if you let us - we like Cardamom Coffee - add cardamom pods to coffee in grinder for a unique spicy coffee. with real dark chocolate.
Writing coffee with the "coffee cup stains" is nice. The original stain that makes the "C" was probably enlarged to create the "f", overlaid to create the "e". The nice brown color that remind us of real coffee stain.
