Heat half of the sugar in a saucepan over a gentle flame,mixing with a wooden spoon until the sugar has melted and well browned. Remove from the heat and let it cool slightly. Add the milk and bring it almost to a boil. Remove from the heat and mix until the carameled sugar dissolves. Let it cool. With this milk and the other ingredients prepare the ice cream following the basic recipe. Serve in dessert cups decorating the top if you wish with threads of carameled sugar and a few raisins.
