So nice to see a vegan recipe on Eating Well that isn't a fruit smoothie or chia pudding!
I added a little more salt than the recipe called for to make this broth more palatable. I also used red cabbage rather than green, given that it was what I had on hand at the time. Don't feel that it effected the taste but it definitely contributed to the broths darker brown color, making it look more like beef stock.
This broth is a good base but it will definitely benefit from savory miso tares or just plain ol' msg in a pinch (it's not going to kill you!)
