I like to use "ghee", or Indian clarified butter. Works great, you don't get the milk fat solids and it gets along great with my trimmings. I use about an ounce of good trim with Betty Crocker's Dark Chocolate Brownie mix. I just clean it, grind it up and fry the leaf in ghee for about 15 minutes. Let it cool and add to mix. I also add chopped walnuts. Cook it at slightly lower temp and longer then the instructions. Check for doneness by inserting a toothpick. If it comes us clean, it's done. Yum!
