I am hoping someone knows what brand this. A few years ago I found this mushroom soy sauce. It was exceedingly thick, very darkly colored (almost stained one's fingers, it was so dark and concentrated, and dripped black on lightish foods till it diluted down to merely dark brown), enormously savory and salty enough to make a person shiver. It is the best soy sauce I've ever tasted.
I bought it from a small asian food shop where I was at school, which has since closed down. I remember it was called mushroom soy sauce, (possibly descriptors like dark or superior(?) in there), but I don't recall the brand, and I don't have a picture. If it helps the bottle label was pale, yellow or gold or tan, non-english characters, with a red cap, and the bottle looked brown but was actually clear, just glazed with sauce inside.
So, I would like to know how to get either this or some similar kind of soy sauce. Some of the various brand's mushroom soy sauce descriptions I find online include different descriptors or reviews that mention terms like sweet, or light, or bitter or sour, which I'm not looking for or recalling in the sauce I had, and descriptions are not always consistent across reviews. Soy sauce in the grocery stores seems pretty thin and sloshy, even tamari which is reportedly on the very dark and savory end of soy sauces. I wouldn't mind liquidy if I knew the flavor would be quite strong, but I don't know how to tell.
I would really rather not buy a half-dozen different soy sauces to find what I'm looking for. I would like to know what sauce (brand) this is, or what product(s) might be generally available^ that would be very close^^, if the original is not findable or not commonly available.
^ Preferably in regular non specialized grocery stores (USA, PA if that helps), or large, easily findable and navigable online websites with non-exorbitant shipping.
^^ thick, dark, strongly-flavored, salty, savory. Preferably not sweet. Would take a product that's liquidy or non-mushroom if it's also strongly flavored, salty and savory.
