Aesthetically and for their richness of flavour. Feels more sophisticated and deeper than many common plums to my part of the world, like yellow or Doris.
Their green streaks are a beautiful complement to deep purples and blood reds - their insides are also lovely and bloody often. Tart little skins, they seem to remain more taut and less watery than many and tend to have a cute and satisfying nub at the end; heart shaped and juicy. :)
some people go their whole lives without experiencing something they want to do or allowing themselves to try something. the rules are made up. you are not too old for anything
