Jaws.

Wyeth, Apples on a Bough, Study Before Picking, 1942

Before the end of December, generally, they experience their first thawing.  Those which a month ago were sour, crabbed, and quite unpalatable to the civilized taste, such at least as were frozen while sound, let a warmer sun come to thaw them, for they are extremely sensitive to its rays, are found to be filled with a rich, sweet cider, better than any bottled cider that I know of, and with which I am better acquainted than with wine.  All apples are good in this state, and your jaws are the cider-press.

Henry David Thoreau, from Wild Apples
