How to make
Crumble the biscuits very finely in a bowl, then add the eggs, sugar, softened butter and cocoa. Stir the ingredients until you get a homogeneous mixture.
Cut the foil to the length and width of your choice. Place the mixture on top, shape it into a salami stick.
Wrap the foil tightly around the mixture and put it in the freezer for a few hours until it hardens. Serve cold.
