Dissolve cocoa powder in coffee and steep raisins in coffee mix until ready to use.
Preheat oven to 375 degrees. Toast almonds pieces on a pie plate in one layer for approximately 13 minutes. Watch so they are toasty brown but not burnt.
Melt butter in microwave. Break the chocolate bars into bite size pieces. Add about ¼ of pieces to hot butter and stir until pieces are melted. Continue to add chocolate pieces. Microwave about 20 seconds at a time as needed until all the chocolate is added and melted. This should only take a couple of minutes. Be careful not to burn the chocolate in the microwave.
Place biscuits in a resealable bag and use a rolling pin to coarsely break them up. Don't get them too fine or they will make the end product too dry.
Mix the biscuits, raisins & coffee mixture, nuts and melted chocolate, icing sugar, sea salt all together in a bowl. Don't overwork just stir until evenly mixed.
On a piece of plastic wrap spoon the mixture into a long log about 12" long. Form the mixture into a sturdy log resembling the shape of a salami. Dust with reserved icing sugar. Seal up the plastic wrap and twirl the ends. Wrap with another piece of plastic.
Refrigerate overnight.
Slice and serve!
The log keeps well wrapped air tight for a couple of weeks in the refrigerator.
