# Put
flour,
sugar and
cocoa into the pot, mix them at first, add cold
milk onto the mixture and mix, place the pot over medium heat.
# Cook it over medium heat by stirring constantly. Remove it from the stove when it reaches to the consistency of
milk pudding and holes become on the surface.
# When it is hot yet, add finely broken biscuits, finely grated
orange rind and thickly pounded
walnut into the mixture, and stir.
# After cooling the mixture in the pot for a while, pour it onto the aluminium foil which was laid over the bench.
# Cool it down on the foil. Just before it turns to cold, smoothen the dessert and roll it with the foil. Close the edges and its top carefully.
# Rest it in the freezer overnight at least.
# Remove the foil, slice and serve. You can serve it in a few weeks if you rest it in the freezer.
