The list of five jellies by itself looks rather artificial and because of that requires serious examination.
Curiously enough, in all editions of the story there is a misprint in the third letter of the third label—beech plum instead of the correct beach plum—but it is impossible to tell whether this was intended or not. [Note: Neither this edition, nor the online New Yorker edition contain this misprint.]
As Carol M. Dole observ[e]s, “the last letters of the four jellies in the list (apricot, grape, beech plum, quince) form the word theme” […], but again this could be a coincidence.
