Interesting!! I have never heard of this one, but to this day I never have met any kind of mushrooms that I didn't like, I would love to try that, too!!
is what they say about "Judas Ears", I checked several sites and they had exactly the same text!! (according to them, we may need to extend our research to "wood ear" or "tree ear" mushrooms...)
If I were you I would just experiment in any way I feel like, first soak it and see what kind of aroma it produces and the texture, and then probably try that in either risotto, stir fry or sauce.
I will look around some more and also ask Cris if he knows anything about it, and I look forward to seeing if anyone has suggestions here!!
(p.s. do you like my olympic avatar?? )
