Those Last Persimmons
Want to savor those last glorious fruits at your whim months from now? Freeze 'em. Simply wash them, wipe off most moisture, and set (stem down) on a flat surface in the freezer. When completely frozen, gather them into a bag or otherwise place them around the freezer. (They don't damage easily since they're rock hard, including the normally delicate skins.)
The night before you want to eat them, transfer them from the freezer into the refrigerator or onto the kitchen counter. Place them in a shallow bowl, since they'll exude some liquid as they defrost. Since their individual cells burst as they froze, now they're oozing their syrup. The freezing process even seems to tone-down the astringency of not-quite-ripe hachiya (heart-shaped) fruits. The flesh will appear "melted" and mushy, but the flavor will still be like you just picked it, deliciously fresh and slurpy. Yum!
