In a food processor or blender, grind the biscuits and chocolate completely, and chop the raisins finely, soaking them in rum for 10 minutes.
In a bowl, mix the ground biscuits and chocolate with all the other ingredients.
It's best to mix the mixture by hand to evenly distribute all the ingredients.
With wet hands, shape the chocolate candies to your desired size.
You can roll the chocolate candies in ground raw nuts, coconut flakes, or anything else you find suitable and tasty. The candies in the pictures are rolled in cocoa.
