Hey all! So there was a Japanese restaurant in my college town that had the most amazing osomashi soup -- a clear broth with scallions, fish cake, noodles and MUSHROOMS. Sadly, I've graduated and moved across the country, so I can't get my fix whenever I like. I woke up this morning thinking about this soup, and specifically the glorious, glorious mushrooms they used -- earthy, sweet, slightly chewy, incredibly umami, tender, amazing mushrooms. Could anyone hazard a guess as to what they were? They were served in slices so I'm not sure of their original shape, but I suspect they were reconstituted (because of the chewiness), and definitely had a deliciously sweet note to their flavor -- unlike any mushroom I've had before. I have a variety of pretty well-stocked Asian grocers around, so if anyone can tell me what they were I'm sure I can find them somewhere. Thank you so much!
