Marvellous and delicious! I made these for dessert tonight using Bourbon biscuits(These are my childhood favourite and I enjoy then till now. I removed the cream from the biscuit and then crushed the plain biscuits to obtain what has been mentioned in the recipe as 'crushed sweet biscuits'). In addition to all the ingredients mentioned, I also used 15tbsps. of grated coconut. There were 2 reasons for using coconut - 1) I had it ready on hand, and 2) The mixture of all the other ingredients did NOT cease to stick to my hands; it required something to bind it all well together, and so since coconut and chocolate is something I love the combo of, I went for it and I'm so glad I did!) and they were well enjoyed by everyone in my family. Thanks so much for posting this recipe. I loved the strong taste of rum alot in these balls. When I had one, it made me want to go grab another :) Really good candy!
