So what is it?
Umami by the way is described as the name for the taste sensation produced by compounds such as glutamate, and are commonly found in fermented and aged foods. In English, it is also described as "meatiness", "relish" or "savoriness".
The rest are self explanatory.
Mine will have to be a cross between saltiness and Umami... but in the end saltiness wins out.
