Picnic food. How does picnic food mimic the editing process of a poem?

The genesis of perfect picnic food is what's in the refrigerator in real time. Here you go -- open said refrigerator (take notes as a detective would), take something out, put the remainder back. You have more; you have less. You are no longer clueless.

The page or digital screen is the refrigerator. Take something out; put something back (sometimes even the same amount). You have been editing that sweet, dear or spicy poem all morning and now you are ravenous.

Begin at the beginning -- open the refrigerator.
