Limes

The astringent has it place.  Often in demand.  Squeezed on avocado or chicken.  Or the combination.

The astringent in poetry?   A leanness, leaning toward a bite.  Not bitter.  No sarcastic.  A defined line
and minimal.   And, yes, the color:   no complaints, there, especially for those back East.  Perhaps, cold is a subset of astringent?

A shout-out to Mrs. Green for another bag of beautiful, bold limes.
