BAA stands for BRAGG Amino Acids. It's wonderful stuff. It's a brown
liquid, kind of like Soy Sauce, but not fermented, and very tasty,
though quite salty. I get it at various health-food stores, but I live
in California. It can be purchased in a spray bottle, but I just use
the big plastic squirt bottle when I'm cooking. It seems to go with
most savory dishes. Hope this helps.
