What are Somen Noodles?
Who wouldn’t want a bowl of somen (Japanese white vermicelli noodles) on a hot summer day? Boil a generous amount of somen noodles and put them on a glass plate. Then place several pieces of ice on top. Prepare your favorite dipping sauce and condiments such as chopped ginger and green onion, and your meal is ready. Cool somen whets your appetite even in the heat of the summer, so be sure to prepare a good amount. Somen noodles are slender, so don’t cook them too long. Cooking takes only about a minute and-a-half to two minutes. Boil plenty of water on high heat in the largest pot you have, and gradually drop in the noodles. Slowly stir the noodles for a while to keep them separated. When the water boils again, reduce the heat to prevent the pot from bubbling over. After that, the somen is ready almost immediately. Quickly transfer the noodles to a colander. Wash them gently with a massaging motion under cold running water to remove the sliminess and enhance the flavor. We love somen because it’s so easy to cook.
The History of Somen
When did we start eating somen noodles? One theory is that a snack brought from China in the Nara period (710 – 794) was the origin of somen. It was made by kneading flour and rice powder with water and salt and forming into dough into the rope shapes and then drying them. The dough was then steamed or boiled and eaten with soy sauce, miso (fermented soybean paste), vinegar, etc. It was also fried in oil and eaten as a sweet treat. The fried ropes look like the twisted donuts in the U.S., so we can’t help but think that some shapes have a timeless, universal appeal.
Incidentally, this snack (called Sakubei) was eaten on the annual Tanabata Festival day (when, legend says, two stars in the Milky Way, Vega and Altair, rendezvous). The custom apparently continued after the dessert became what we now know as somen, because Japanese still eat somen on Tanabata out of respect for Princess Vega.
Reportedly the original snack fell out of favor because the dough was too soft and difficult to cook compared to somen as we now know it or udon (thick white noodles) and didn’t keep long enough as dry noodles. During the Kamakura period (1185 – 1333), noodles made through a completely different method arrived from China. They were made from only the finest flour and milled by a machine. Vegetable oil was also used to keep the noodles from drying as the dough was stretched many times into long, slender noodles. The noodles, held together by a network of gluten, were firm and retained their shape after cooking in boiling water. In the Muromachi era (1336-1573), quality somen noodles were made using a better method and tools; these noodles remain popular today.
Making Somen Noodles
Somen is a product of three simple ingredients: flour, salt and water. Flour is kneaded with salted water to make a noodle dough. The well-kneaded noodle dough is flattened and stretched using a rolling pin or by stepping on it, after which the dough is cut to around 1.7 inches thick and twisted into a rope shape and then looped in a tub. Next, the dough ropes are pulled from the tub and put on a plate, brushed with vegetable oil, then returned to the tub. The dough is then aged in the covered tub.
The aged noodles are placed on a stretching tool and stretched thinner. The thinner noodles are then looped around two bars in a figure-eight shape. These twisted noodles are aged again, and then they’re gently pulled and stretched. This aging and stretching process, which makes the noodles firm and chewy, is implemented slowly or repeated multiple times to achieve the finest taste.
The aging process is followed by drying in the sun. The noodles are hung from a drying machine that looks like washing poles more than 6.6 feet high. Chopstick-like bars separate the noodles to prevent them from sticking together as they dry. In this process, experience and technique with an understanding of the weather and wind direction of the day are needed in order to dry the noodles evenly. The fully dry noodles are then cut with a knife and divided into serving bundles, which are then wrapped in strips of paper. The somen noodles made by this time-honored method–which is still used today—are called tenobe somen (handmade somen noodles).
Difference between Somen and Hiyamugi
Incidentally, do you know there is a difference between somen and hiyamugi which are often considered the same thing? They appear to be identical, having the same shape and same color, but the two are actually very different in terms of their histories and production methods.
Hiyamugi is made roughly the same way as udon. Flour dough is rolled with a rolling pin and cut with a knife. Unlike somen , hiyamugi isn’t coated with oil or dried in the sun. Evidently, hiyamugi is a cousin of udon but not of somen.
The current JAS (Japanese Agricultural Standard) standard in Japan differentiates “somen,” “hiyamugi” and “udon” by thickness alone. Specifically, noodles less than 0.05 inches thick are called somen, those 0.05 inches to less than 0.07 inches thick are called hiyamugi, and those 0.07 inches thick or thicker are called udon. This classification is probably a way to accommodate variations, such as local variants of somen that are made without oil and udon that are stretched by hand. Moreover, some manufacturers have mixed noodles of pink, green, and other colors into hiyamugi to differentiate them from somen, although this practice is somewhat rare nowadays. Today, colored somen noodles are occasionally mixed into white ones to make them attractive for children.
Different production methods lead to different tastes, textures in the mouth, and nutritional values. The process of coating the noodles with vegetable oil and twisting them generates a wheat protein called gluten. To make slender noodles without using a machine, handmade somen noodles are “twisted” many times.
This is why handmade somen is an excellent source of gluten. In fact, somen has more calorific value and contains more protein and sugar than udon or hiyamugi. In addition to being cooling and tasty, somen is a perfect high-nutrition food that saves us from the lethargy of summer heat. It’s another example of the wisdom behind Japanese food–cuisine that is known for selecting the freshest ingredients in season or materials appropriate for different times of the year.
Types of Somen Noodles
Currently Banshu (Hyogo Prefecture) is the number-one handmade somen producing region in Japan. Reportedly, the quality wheat produced in Harima, the famous salt of Ako, and the clear water of the Ibo River is what made somen-making popular in Banshu. The most famous brand of somen in this region is Ibo no Ito. This brand of somen is owned by the Hyogo Prefecture Handmade Somen Cooperative and is only available locally. When somen production gained momentum around 1900, the Cooperative trademarked the name “Ibo no Ito.” Sales of Ibo no Ito gradually increased, and although the production volume dropped substantially during World War II, output resumed afterward. Today, Ibo no Ito is a respected traditional somen brand.
It is worth mentioning that the Cooperative requested that the title of “Handmade Somen Technician” be recognized as a national credential. The request was approved in 1993. This is understandable, because somen production requires expert skills. Thereafter, handmade somen manufacturers throughout Japan began labeling their products with the names of their Handmade Somen Technicians. Consumers can now put a face on each package of somen, and they can clearly see whether the somen noodles are handmade or machine-produced.
Another somen brand with a long history is Miwa somen. The Miwa Ward of Sakurai City, Nara Prefecture, is known as the origin of somen, and they say nearly all materials used in various somen-producing regions across Japan come from Miwa. One unique aspect of Miwa somen is that the noodles are stretched using cottonseed oil because, in the old days, cotton flowers were produced in the area. Actual production was small and most somen sold in Miwa was produced in Shimabara, Nagasaki Prefecture. Today, companies label only the noodles produced in Miwa as Miwa somen.
Somen by Region
A less renowned contributor to the popularity of Miwa somen is the variety from Shimabara, mainly from Shimabara City, Nagasaki Prefecture. Shimabara is a little-known somen- producing region that has a long history of producing Miwa somen. That’s why the handmade somen noodles from Shimabara are of high, stable quality but are priced affordably. Nijiya Market carries “Yamada no Shimabara Tenobe Somen,” one such somen brand from Shimabara. This premium somen product is made from an original powder mix jointly developed with a local flour mill and using the clear spring water and the choicest salt of Shimabara. The noodles are made with the craftsmanship and careful attention of Toshio Jingawa, a “Modem Master Craftsman” recognized by numerous awards including the Nagasaki Governor’s Award. Be sure to try these doughy, chewy noodles that don’t become soft after cooking.Various other types of somen are available throughout Japan. Shodoshima Tenobe Somen produced on Shodoshima Island, in Kagawa Prefecture, is stretched using sesame oil, which doesn’t oxidize easily and can therefore be aged for a long time. Shodoshima, the third largest somen-producing region in Japan, is home to the Shima no Hikari brand of somen noodles, whose authentic taste has many fans. Somen is also eaten in many different ways. One well-known style is “nyumen,” which involves pouring hot sauce over the noodles. Most common in the Nara and Saga prefectures, this style of eating somen is popular throughout Japan. Various flavors can be enjoyed by using Chinese-style sauce or frying the noodles beforehand. In Miyazaki and Kagoshima prefectures, nagashi somen was born after World War II. In this style of eating somen, the noodles are dropped into running water. The flowing noodles are then picked up with chopsticks and dipped in a sauce. The scene of family and friends eating nagashi somen together on a hot summer day is familiar in Japan.
Nijiya sells a premium somen sauce made in Tosenkyo, one of the leading nagashi somen regions in Kagoshima, as well as Murasaki-imo somen made with murasaki-imo (purple potato). Enjoy the authentic taste of nagashi somen right here in America.
How to Enjoy Somen Noodles?
You need a tasty somen sauce to enjoy somen. Somen sauce is basically made from bonito stock, but it differs from regular noodle sauces in several ways. Because somen noodles are slender and easily hold a sauce, somen sauce is made less salty. Water in which dried shiitake mushrooms have been soaked adds a great flavor to somen sauce. It’s also a good idea to add slices of shiitake stewed in soy sauce and sugar. The umami of shiitake comes from guanylic acid, which, when combined with inosinic acid, enhances sweetness. Cooking dried shiitake mushrooms takes time, but it’s worth the effort.No matter how much you love somen noodles, you may find it boring if you always eat them just with sauce. To make the somen experience extra fun, pay attention to the condiments that go with the sauce. Standard condiments include finely chopped green onions, myoga (Japanese ginger), and ginger. To increase the cooling sensation of somen in your mouth, try it with grated daikon (Japanese radish) or julienned shiso (perilla), cucumbers, and tomatoes. Thinly sliced omelet or scrambled eggs add protein for better nutritional balance. Another idea is umeboshi (pickled plum), which is an ideal accompaniment of somen to fight the lethargy of summer. The sourness of umeboshi has an amazing ability to refresh and rejuvenate the body.
Gooey foods are popular these days due to claims of their healthful benefits, and they go perfectly with somen too. Mix grated yama-imo (Japanese yam) and sliced okra, and place them in the somen sauce. You’ll soon become addicted to the gooey texture that bursts in your mouth. Also, mixing in natto (fermented soybeans) or tororo kombu (kelp flakes) enhances flavor and boosts the nutritional value of a somen meal. Another interesting idea is to mix chopped leaves of molokhia, which is in season during the summer. Molokhia is rich in vitamins and is said to lower blood pressure. For those of you who love spicy foods, kimchi is a must-have with somen. The spicy pickled vegetables turn somen into reimen-like noodles (Korean noodle dish). Red chili pepper in kimchi makes you perspire and therefore cools your body, which is what you need on a hot day. Add shishito (grilled green peppers) or wasabi (Japanese horseradish) for a delicious accent. If you want to make a filling meal for growing children or young adults with good appetites, add sliced ham or cooked chicken breast.
A fun aspect of eating somen is that you can enjoy it with many different condiments you’re limited only by your imagination! It looks like we’ll have another hot summer this year. Why not prevent fatigue from the summer heat by eating delicious somen?
