Simply delicious
Documentary evidence indicates that preserving persimmons by drying dates back at least 160 years in Hsinchu. Taking advantage of the powerful northeasterly monsoon winds that spring up in late October, local Hakka residents have long treated persimmons with the elements of sunlight, cold breezes, and time, to turn unbearably astringent fruits into sweet, soft and chewy persimmon cakes.
Lu Li-chien, owner of Weiweijia Persimmon Farm (Pro Persimmon), who has been making persimmon cakes for 40 years, says: “Persimmon dryers love cold fronts. Sometimes the northeasterly monsoon blows for a whole week, and we can rest easy at night. But we really worry about dew.”
Persimmon cakes made from the “stone persimmon” (shishi) variety are sweet with a chewy texture, while those made from the “bull heart” (niuxinshi) variety are large and fleshy. Many years ago Lu successfully adjusted the sun-drying time and oven-drying temperature to dry the “pen persimmons” (bishi) harvested in Taichung’s Dongshi District each December. Epicures with a sweet tooth know that you have to wait until December for the sweet, soft, and chewy pen persimmon cakes to come on the market.
Specialized freezing technology is also used to dry persimmons. As the moisture slowly evaporates from the fruit, the sugars within it form a layer of white powder on the surface. This is natural “persimmon frost,” and the dried fruits can be combined with traditional Chinese medicines like wolfberry to make a chicken soup that can “clear heat and dissipate phlegm.”
Dried persimmons have diverse textures and degrees of sweetness, depending on the persimmon variety used. The persimmon cakes at right in the picture are made from those shown at left by further drying until their water content is around 30%. They can be combined with medicinal herbs to make a healthful soup.
