I rely on "Better Than Bouillon" bases.  I can use the exact amount I need without cutting up hard cubes.  The flavor is consistent throughout the base and does not settle out--it will never separate the flavor from the salt from the liquid and fat; not even when left on the refrigerator shelf for months and months.  That is important to me.  The base is very easy to spoon out; it doesn't harden in the cold of the frig.
