KnorrTom Yum Seasoning Bouillon Cubes 24g, (Pack of 24)

Are the cubes dry or moist? Can I crush the cubes into a powder?

What are the ingredients?

I'm sure these are a sodium bomb, but what are the nutritional facts on these? how can they be sold to us customers without disclosure?

How many cubes do you need to make a liter of tom yum soup? does this have an authentic tom yum taste?
