"The idea of chocolate pasta may sound strange, but once you try it you will love it! The great thing about homemade pasta is that you can flavor it any way you like. It is excellent served cold and can be made in advance for a quick dessert. Top it with whatever you like. Try adding raspberry sauce, or raspberry sauce with a little bit of liqueur mixed in. Toss the pasta with Grand Marnier or Amaretto, chocolate sauce and top with fresh whipped cream for a delicious treat."
