By timbre. Yes, sometimes raspy.
By design. Recalling the work of honeybees and their hives.
By taste. A poem must feel just so in the mouth.
By example. Exemplary of the ripe.
Breakfast soft corn tacos
mix: raspberries, golden cherry tomatoes, snippets of basil, cubes of queso fresco, a twist pepper
warm the corn tacos over stove's flame (electric? out of luck)
the poem will soon reveal its color, timber, physicality, and above all, ripeness
