Heck, I used everything but the nut meat. Too much sugar and causes a biology experiment. But mainly just the outer husk. I also made some coffee dye. I cheated and used instant. One jar to a quart of hot water came out a nice tan. Then, in an inspired moment, mixed in a pack of Kool Aid, raspberry I believe. Made a brilliant tan, but, dries out the leather horribly. I presume the citric acid, but, a little EVOO brought it back. Looks good. I've got a holster in here somewhere that I dyed with it.
