I used to sprinkle a mushroom extract I bought from China Town on all sautéd greens and stir fries because it just made all things taste better......that is until I found out it contained MSG. I threw out the whole packet, but really missing the umami depth it lent to my veggies.
Not long ago I came across a blog that suggested making your own mushroom extract. Why didn't I think of that?
I combined dried porcini mushrooms with dried shitake mushrooms (stems removed) in a food processor. In a few minutes I created my own MSG free mushroom extract. It has become one of my spice rack staples and I use it for everything from sautéd kale to veggie stir fries to soups!
