I have just made this up tonight from stuff in my cupboard and some cheap parma style ham i had in my fridge. I am trying not to go shopping and having to spend money so am using what I have. You can buy dried portini musrooms quite cheaply (don't forget to soak them first). I get my parma ham from a German discount foodstore beginning with L. You could use single cream instead of creme fraiche and you could use different dried Italian herbs. You can double quantites to serve four.
