I used to buy a sauce at the market where I used to live and I can't find it online anywhere. I believe it was a bonito concentrate. I don't recall the name but it came in a tall plastic bottle, kind of like a water bottle. It was dark brown, had a very intense smoky flavor and had a consistency kind of like ketchup. As I recall it had a orange label and maybe had a drawing of a fish on the side. Does anyone know what this is? I would love to find it online. It wouldn't have to be the same brand but I would like to find the same type of sauce.
