I'm cooking for a friend that, for medical reasons, must eat vegan, and soy-free. I was really wanting to make a vegetarian stir-fry for her, but I can't come up with or find any sauce that would be good in a stir-fry without meat nor soy-sauce. Must be too dependent on butter+soy sauce myself. =P
I was thinking, I'd add mushrooms to the stir-fry to get the umami, use sherry+veggie broth to create the liquid, and using ginger+garlic+salt for flavor, but that seems like it'd be too light. There must be some way to get that dark rich flavor of soy sauce without soy?
