For quick truffles, just make "Dirty Truffles". Make a batch of dark ganache like Kahlua and dont dip them, just roll in equal parts cocoa powder and instant coffee (I like Medaglia D'oro Instant Espresso.) Another fun one is dark ganache with wasabe. Roll in 2 parts cocoa powder and 1 part powdered Ginger. If you have any 23k gold dust mix in some of that for interest. Get creative with the dry coatings, nuts, cocoanut, potaote chip crumbs or black pepper. PS. Put the ganache in a glass 9X9 and put it in the fridge for an hour or so. Then scoop out and roll, coat with powder coating, Done!
