Dried mushrooms rehydrate as you slow-cook this classic Chinese soup, giving the broth deep umami flavor. With the addition of cooked noodles at the end, it’s a satisfying vegetarian meal. —Food52

I almost didn't make this because of the previous reviews and I really should have followed my instincts. It was flavorless and really not good at all. No one at our house liked it. My recommendation is to try another recipe instead.

Very easy to halve this recipe. Just like going out for hot pot.

As I had no bamboo shoots I added a sliced fennel bulb. Am partial to fennel.
Also omitted cornstarch.
Did not add noodles as this makes much soup and I do not like gluey noodles in second servings. They are better added as needed.
Next time will cut down dried mushrooms by half and add fresh ones to compensate.
Used 4 garlic cloves and Korean hot pepper paste as have no chili-garlic sauce.
Sriracha is also possible but the Korean sauce is more complex.

Thank you, Harry.
Much appreciated especially as I rarely comment.

I followed your instructions and it was actually really good this way!

I followed this recipe exactly and would not make it again. There are a few problems. 1. Called for dried shiitake mushrooms and in step one it says to cut the caps and remove the stems. Not really possible with dried mushrooms. 2. The recipe doesn’t actually say to cook the noodles. 3. Doesn’t say when to put in the scallions. I threw them in at the end. None of this is earth shattering but it just wasn’t that good.

To be fair I keep my pantry well stocked with many Asian items so little shopping was required. Also, I'm terrible sticking to vegetarian dishes so I replaced the water with a simple dashi broth, added ground Szechuan peppercorns, and replaced the red wine vinegar with Chinese black vinegar (similar the balsamic in flavor). For those not so familiar chile garlic sauce is also sold as sriracha or for less sugar use sambal.

Trying this tonight. Could not for the life of me find dried shiitake at the Asian grocery store, so using fresh shittake and portabellos. Will update later after we eat it.

I really wanted to like it, but it just wasn’t that great. The cornstarch and noodle combo made it slimy. Not the best flavor....will not make again.
