Need help finding an asian vegetable, or rather a herb
I am trying to locate an Asian herb. My step-mother is Vietnamese, and she used to use it in Vietnam, and actually has seen it in some Asian food stores. I do not know what it is called, but I can describe it. It has a "fishy" smell to it, and it is used in soups and seafood recipies. I have only seen it prepared, but it seems kind of viney. The leaves seem to reach a silver dollar size, or possible a little larger. My step-mother said it is suppose to be related to coriander, but I don't know have reliable a source she is regarding this subject. She has not told me the Vietnamese name, so I can't give that to you.
Does anyone know what kind of herb this might be? I will try to get the name out of my step-mom, but I wouldn't hold my breath for it.
