You can make this into the caramel you wanted. Melt 25g of butter in a pan, add 50g of granulated sugar and stir till the sugar melts. Add the condensed milk and stir over a medium heat for about 10 to 14 minutes, make sure to stir around the bottom of the pan so it doesn't stick. Continue to stir until it turns brown and thick. Make sure it is thick enough, then leave to cool before using.
Get dessicated coconut, chopped frui and nuts, and put into bowl with the condensed milk, stir well, put into shallow baking tin, and cook till lighly golden. Whilst still warm, top with grated chocolate, and leave to cool. When cold cut into squares, and enjoy - delicious.
