Mushroom seasoning is used widely in a lot of Asian cuisine, to enhance the flavor of the vegetable dishes. I discovered this seasoning when my neighbor and dear friend back in Singapore, Yew Hong, introduced me to this store selling all kinds of products for vegetarian cooking. It resembles light brown granules and it is mainly made of dried mushroom and used in place of MSG without its side effects...It comes in convenient sachets, containers and packets of various sizes and is available in many Asian stores around the world.
I use it quite a bit in a lot of my Chinese or Thai cooking...it is a life saver for vegetarians because it gives a natural flavorful taste to many dishes. And it has a lot less sodium than other seasonings. Because it comes in concentrated dry granules, use it SPARINGLY! You can always add in more later per your taste preference....
