Hoshigaki are a Japanese delicacy made by gently massaging persimmons while they air dry.
The persimmons used to make Hoshigaki are astringent varieties such as Hachiya. Ideally, choose fruit that still has part of the stem. We've used a couple different varieties of persimmons with nice success.
1) The first step is to cut the top off, while carefully leaving the stem that you will tie string to and they will hang from. And then use a knife of peeler to trim away the skins of the persimmon. Then attach the string and find a good place for your Hosigaki to hang. Broom handles work great for this, we've also used knitting needles, drumsticks and hangers to hang the Hoshigaki from.
2) The first week you just let the Hoshigaki hang and dry till they start to create a thin skin. After a week has passed you begin to gently massage each persimmon every other day. Be careful not to break the skin.
3) As you keep massaging every other day the fructose in the fruit will begin to come to the surface. The "bloom" begins to appear...it looks like powdered sugar on your persimmons. Keep massaging until the persimmons are more like a dried fruit, changing into a darker color with the bloom, and then enjoy!
