Choclate and Caramel is the best combination and with a crunchy base, its extra special. It keeps well in the fridge for a few weeks. To marble the chocolates, pour the dark chocolate over the caramel and before it sets pour white chocolate over it and with a knife marble it! To get a more traditional look, pour white chocolate in lines and then with a scewer stroke it alternatively left to right and right to left and allow to set.
