This recipe has the most amazing saffron sauce! Although it calls for shiitake mushrooms, I've made this with Oyster mushrooms and it is equally good, but you need to add some color. Red or orange bell pepper, julienne usually does the trick. Portobellas are good too. I always reduce the amount of heavy cream in this (by half!). If you don't have fettuccine, this is really good with bowtie pasta. An oaky chardonnay goes well with this. From Food & Wine, Pasta.
