I do not know... But you sparked an interest... As I do roast Macadima nuts on occasion..
A quick Google got this...
I will leave it to you 2 do some more research and get back to us...
beans are generally roasted in what is referred to as "butter oil", which may or may not be actual clarified butter oil. Occasionally vegetable oils are used, and historically, traditional "home-grown" coffee roasting style involves creating almost a caramel-like coating effect with the use of a small amount of sugar, oil, and generally a touch of vanilla or cocoa. This coating blackens in the roast and the beans wind up with almost a thin, hard shell.
