Chestnuts are one of China’s native crops and have been cultivated there for millennia. They are grown in many parts of the country, but particularly in the north, where they are used in soups, stews and stir-fries, or ground into flour for breads and sweetmeats. Chicken and chestnuts are a classic Chinese combination. One September morning, I drove out with my friend A Dai into the Zhejiang countryside, through a lush greenness of paddy fields, bamboo groves and lotus ponds, into the teabushed hills. Up a rough track we left the van and walked out into the twittering, humming undergrowth. A little further and there was an orchard of chestnut trees, where we plucked the prickly fruits and peeled open and ate, raw, some of the crunchy young nuts. Later, back at A Dai's restaurant, we tasted more of them, stir-fried with ginger and the meat of a young chicken, a tender dish that can only be enjoyed early in the chestnut season. When the nuts are plumper and more mature, they find their way into braises such as this, perfect for a winter's evening. In China, this would be made with a whole chicken, chopped up on the bone, but this quick version is made with boneless meat. Prepare it in advance if you like and reheat just in time for your meal.
