So I get this vegetarian Tom Yum soup at my local Thai Rest. that is Out of this world!!! It tastes excellent, and I just can't duplicate it at home. I got the ghalangal (sp?), lime leaves, and lemongrass, but how to I give it that "sweetness?" It isn't a sugar sweet, it's different.. like a carrot is sweet. Maybe they just put sugar in it, I don't know. Also, does anyone have any other flavoring and technique ideas that don't include shrimp, fish sauce, or chicken stock? Thanks.
