Season for chestnuts!

Season for chestnuts!

Roasted chestnuts are cold weather comfort food. On the streets of Beijing, tiny hole-in-the-wall shops with big black drum roasters or huge iron woks are once again sending out the tempting aroma of caramelized chestnuts.

They are seasonal vendors. For the rest of the year, the drums are silent, the woks are cold and the shopkeepers sell dried fruits, melon seeds and other tidbits. Only after the autumn harvest does the roasting begin in earnest.

If you take an excursion out to the Great Wall at Mutianyu, you can see native chestnut trees beneath your feet as a cable car carries you to the hilltop. Tourists visiting the Ming Tombs, too, may rest unaware beneath ancient chestnut trees. 

Chestnuts are often used in Chinese cuisine. Photos Provided to China Daily.

But the trees are there, distinguished by their dark green ovate leaves with serrated edges, or their skinny catkins in flowering season. The easiest time to identify chestnuts is when the fruits ripen and fall to the ground.

The reddish brown nuts, two to three in each thorny case, will peek through a prickly shell called the burr.

In my old campus stomping grounds, there were plenty of stately trees in the park, and Asian students would gather the fallen fruits, stepping on the burrs to release the nuts to save their fingers from the barbs. American chestnuts are much larger and need to be sun-dried a bit to sweeten them. Otherwise they taste floury.

We did not have the equipment to roast the nuts, so we simply cranked up the oven and baked them. I even experimented with grinding the nuts into powder and making bread and chestnut cookies, which worked pretty well.

Strangely enough, no one else but the squirrels bothered to pick up the chestnuts, and so we were left to enjoy the free bounty.

In China, not a nut goes to waste. Even wild chestnut trees are carefully monitored. When the burrs fall, they are hastily foraged.

The best chestnuts are from Liangxiang in Fangshan, a southwestern suburb of Beijing. Liangxiang chestnuts have become well-known and are sold all over the country. They're even exported.

Tianjin also produces chestnuts and the farmers there have carefully packaged their nuts in ready-to-eat vacuum packs that are sold in the city's souvenir shops. You can see these at airport duty-free shops all over China.

But ask Beijing locals and they will swear by the chestnuts from Huairou, an outlying county that is well known for its trout farms and farmers' restaurants. Huairou chestnuts are smaller, but by all accounts the sweetest.

Chestnuts are grown all over China, and the cultivars are all slightly different. Some are suitable for roasting, others are sold freshly shucked at markets for the cooking pot. Still others are harvested, skinned and dried to be sold all year long. The better-quality chestnuts are from Shandong and Fujian. 

Chinese chestnuts are winter snacks. Whole nuts are snipped at bottom end to prevent them exploding during cooking, and are then roasted in a mixture of sand and sugar. They are sifted clean before being sold but are still characterized by the slightly gritty sticky shells. These sweet chestnuts, a deep chocolate brown and glistening with sugar glaze, are a real treat.

They used to be hand fried in huge iron woks, with the vendors perspiring over the hot sand mixture, despite the winter chill. The sand helps to increase the heat needed to pop the nuts open.

These days, chestnuts are mostly roasted in automated steel drums that rotate, rustling noisily as they turn. 

Holding a bag of hot chestnuts warms both hands and heart. And, because of the high carbohydrate content, the nuts also provide heat to the body.

As the nuts cool quickly in the chilly temperatures of winter, they become easier to crack and peel, their dark brown skin coming away from the creamy yellow flesh like paper.

Chestnuts are also used in cooking. They are one of the ingredients in the classic Eight Treasures Duck, together with lotus seeds, shiitake mushrooms, Chinese sausages, leeks, scallions, pine nuts and sticky rice. You could say this is the Chinese equivalent of turkey stuffing.

Chinese chefs go one better. The duck is carefully boned before the filling is stuffed into the bird, steamed and then flash fried to crisp the skin before serving. Sometimes, the duck is tied at the neck and at the waist to shape it into a bottle gourd, or hulu, a symbol of good fortune and longevity.

Another classic dish is braised chicken and chestnuts in an onion gravy. It is an extremely popular home-cooked dish when fresh chestnuts are in season.

Unlike the French, the Chinese are traditionally less likely to use chestnuts in patisserie, but the new coffee clubs and cake houses in the cities are now pushing out a popular cake topped with candied chestnut puree similar to marron glac. This pastry first originated in Hong Kong and was in turn inspired by the classic French Mont Blanc.

Chestnuts are also dried. Dehydrated nuts meant that chefs could use the nuts all year, simply soaking them in water before cooking. Dried chestnuts are sold in Chinatowns all over the world.

During the fifth lunar month when rice dumplings are prepared for the Dragon Boat Festival, dried chestnuts fly off the shelves. Every savory dumpling will always need one or two chestnuts to complete the filling.

Like most Chinese ingredients, chestnuts are valued for their medicinal value. Traditional Chinese medicine prescriptions use chestnuts for stomach ulcers and to whet appetites. They are believed to be a yang food and therefore good for virility. Taken in moderation, they aid blood flow and increase qi in the body.

Chestnuts are also said to be good food for women, having the ability to combat anemia and improve complexions.

That's very comforting to know, and for once, I'm sure, most will gladly take the prescriptions and enjoy them too.
