Not sure about "special" coffee and "special" oil but the whole idea about butter fat being avoided for so long.....  This seems like an interesting twist I'm going to try...thought I'd share.  Protein and fat have been vilified for so long and the food pyramid turned upside down in favor of carbs and sugars.  Obesity and diabetes are growing alarmingly.  Somewhere we've taken a wrong turn compounded with a broken food system.  As a culture we seem out of balance...

Thanks for sharing but I agree with you that putting butter in coffee seems crazy.
