Mix throughly the eggs and sugar, add the flour until the compound is smooth, add the nuts, chocolate, candies all roughly cut in pieces and lastly the rum. Mix until all the ingredients are well distributed and put in a long and narrow rectangular oven pot. Bake at 180 degrees Centigrade (moderate fire) until the surface is a beautiful light brown. Take out of the oven and let the cake rest for at least a couple of days. It should be cut in very thin slices just before serving. Accompany with a good Marsala or sweet red wine.
Multiplying the ingredients, you can make more of these tronchetti, that can be kept inside aluminium paper for weeks.
