DELICATE FRUIT SIGNALS ARRIVAL OF EARLY AUTUMN

As summer heat fades and autumn settles over China's Jiangnan region — the area south of the lower Yangtze River — a tiny white kernel begins appearing in markets, restaurant kitchens and family bowls.

Known in Chinese as jitoumi, or "chicken-head seeds", gorgon fruit is one of the season's most distinctive ingredients. Hidden inside a hard, spiky shell, the pearly kernels are tender yet pleasantly springy, with a delicate natural sweetness.

Monday marks the beginning of bai lu, or White Dew, one of the traditional 24 solar terms, which signals cooler temperatures and the arrival of early autumn. For generations, it has also marked the peak season for fresh gorgon fruit in Jiangnan's waters.

At Song, a Chinese restaurant in Hangzhou, Zhejiang province, chef Zeng Donghai puts the seasonal ingredient at the heart of a warming clay-pot dish.

The restaurant's braised taro and gorgon fruit pot with assorted seafood brings together creamy Fenghua taro from Ningbo, Zhejiang, fresh gorgon fruit and pearl abalone.

"The ingredients complement one another," Zeng said. "The taro gives the dish richness, while the gorgon fruit brings a lighter, fresher texture."

Gorgon fruit is more than a seasonal delicacy. Feng Liying, a nutrition specialist, said the fruit contains starch, protein and other nutrients, making it a gentle addition to a balanced diet during the transition from summer to autumn.

For many in Jiangnan, the simplest way to enjoy the ingredient is still one of the best. Fresh kernels are briefly cooked in boiling water, sweetened with rock sugar and topped with dried osmanthus. The result is a bowl that is soft, fragrant and lightly sweet — a familiar taste of autumn.

Gorgon fruit also finds its way into more elaborate dishes. At The Chrysanthemum Chinese Restaurant in Wuxi, Jiangsu province, chefs pair hand-peeled gorgon fruit from Suzhou, Jiangsu, with river shrimp from Gaoyou Lake.

The shrimp meat, roe and tomalley (the mushy substance found in the head and body cavity of shrimp) are prepared by hand before being quickly stir-fried over a high heat. The crisp sweetness of the shrimp contrasts with the soft, chewy texture of the gorgon fruit, while the roe adds a deeper savory note.

Chef Yi Chengfeng said the dish relies less on elaborate seasoning than on the quality of the ingredients and the care involved in preparing them.

"The shrimp roe is scraped out grain by grain, the tomalley selected one shrimp at a time, and the gorgon fruit peeled kernel by kernel," he said.

Behind that delicacy lies months of work. Xu Fengchun, a 69-year-old farmer from Suzhou, has grown gorgon fruit for decades. The crop is planted in spring and harvested only once a year, with picking typically beginning in late July and continuing until around the National Day holiday in early October.

Growing the crop requires clean water, suitable weather and patience. Once harvested, the fruit must be sorted and the tough, thorn-covered shells removed by hand before the white kernels can reach the market.

From a spiky fruit floating on Jiangnan's waters to a pearly white kernel in a bowl or on a restaurant plate, gorgon fruit tells a story of the changing seasons.
