Ripe persimmons ready to dry |
Simply Living
October 29, 2012
Our food dehydrator has been running non-stop lately. Autumn is persimmon-picking season and we have been busy peeling, slicing and drying trays full of the popular Asian fruit.
Native to China but extensively cultivated in Japan,
persimmons are an essential part of Japanese diet with over 1,000 different
varieties cultivated for use in everything from wines and vinegars to baked
goods and candy. Although they were introduced
to North America in the late 1800s by Admiral Perry and have been cultivated in
Florida for over 100 years, persimmons failed to win over the palates of American
consumers.
Perhaps their lack of popularity is due to the fruit’s
astringency factor. Most persimmon
varieties are high in a soluble group
of phenol compounds found in plants called tannins. Other fruits that contain tannins include cranberries,
pomegranates and strawberries. When
unripe, these fruits taste bitter and cause the mouth to pucker up and feel
dry. That changes as the fruit ripens
and the tannin compounds decrease
The small plum-sized Florida native persimmons that grow wild in Central and Northern Florida are especially astringent. Rather than being the type of fruit picked to
eat fresh, wild persimmons are best cooked, fermented or made into jelly or
jam. However, certain varieties of Asian
persimmons (Diospyros kaki) are good to eat right off the tree. In addition to being the same color as
tomatoes, these non-astringent tree fruits also share a tomato’s round, slightly
squat shape.
Picking Hachiya (astringent) persimmons off the tree |
Fuyu is one of most commonly grown varieties of
non-astringent Asian persimmons. When they
are hard, I like to eat them like an apple, skin and all. When soft and a little riper, I prefer to
peel the skin (which toughens as it ripens) and eat the sweet flesh with a
fork.
Instead of being round, astringent Asian persimmons are
heart-shaped. Hachiya is the most
frequently planted variety of this high-tannin-count fruit. In order to avoid the unpleasant dry mouth
sensation, heart-shaped persimmons must be fully ripe and soft to the touch
before eating. When ripe, the flesh is
very sweet with a pudding-like consistency.
I like to scoop out the flesh with a spoon to eat fresh or use in
baking.
This year, we discovered that instead of waiting for Hachiya
persimmons to ripen, we can peel, slice and dry the unripe fruit when it is still
hard and otherwise inedible. It turns
out that heat from the dehydrator removes the astringency by accelerating the
tannin removal process. As the tannin
cells decrease, the fruit’s natural sugars move to the surface resulting in a
somewhat sticky, exceedingly sweet and quite tasty candy-like product.
When dehydrated, the trays full of persimmons will taste as sweet as candy |
This new discovery adds to the many ways our family enjoys eating
this underappreciated, nutritious fruit.
We eat a great many persimmons fresh either whole, cut up in slices or
in fruit salad. Occasionally, I bake
with it, making persimmon bread or muffins but the main thing we do with
persimmons is dehydrate them. We then pack
the dried fruit into small tightly sealed bags and place them in the freezer to
enjoy as a sweet treat all year long.
If you have never eaten a fresh persimmon, now is a good
time to try. While Florida’s persimmon
season has ended, California-grown persimmons will soon appear in produce
departments for the November and December holidays. And if you are one of the people who once sampled
a persimmon but had an unpleasant experience, consider trying them again.
Remember, if it is a round, slightly squat cultivated (non-wild) persimmon, it doesn’t matter if it is hard or soft. At any stage of ripeness, most round persimmons are good to eat. However, if it is a heart-shaped fruit, make sure to wait until the bright orange-red skin feels soft when squeezed before scooping out the flesh and taking a bite.
