Acorn noodles or "dotori gooksoo" are Korean noodles made from acorn flour or starch, salt and a combination of grain-based flour (usually buckwheat or [[wheat]).

Acorn noodles may be made from acorns collected from red or white oak species and each oak species gives a distinct flavour. Labels do not list on the ingredients from which exact tree type the acorns are from, probably due to the large number of oak species and increasinly oak hybridization (especially among white oak varieties). This makes it difficult to recognise and document each type of species.

Origins

Evidence at Neolithic sites such as Amsa-dong in South Korea show acorns were part of the human diet. Acorns contain bitter tannins which would have been leached out to make the acorns edible. They were then ground into flour using a saddle quern and milling stone.

It is unknown exactly were acorn noodles were first produced. However, Ogam village, Korea is well known for a long history of acorn cultivation. The village is nestled by the Namhangang River and is famous for its mountainous climate and landscape, which is conducive toward large-scale acorn cultivation. The village produces dozens of acorn-based foods, including dotori kalguksoo (acorn knife-cut noodles).

Varieties

There are two varieties of acorn noodles available in the market: flour-based soba and starch-based vermicelli.

Starch-Based Acorn Noodles

Acorn vermicelli noodles or dotori naengmyeon (hangul: 냉면 도토리) are made from acorn starch and some combination of potato, rice, or arrowroot starch, wheat flour and salt. The dried noodles resemble brown plastic threads about 1/10-1/8 cm in diameter. Cooked properly and typically eaten cold, acorn-based naengmyeon noodles have a high elasticity and chewy consistency.

Flour-Based Acorn Noodles

Acorn soba noodles or in Korean, dotori gooksoo (hangul: 도토리국수) are made from acorn flour and a combination of grain-based flours; such as buckwheat and corn, and salt. They are about as thick as spaghetti and are used in hot and cold dishes, such as Zaru Soba (boiled noodles are served cold with a dipping sauce.) Acorn soba noodles are more natural and healthy than the starch-based acorn vermicelli noodles. They contain buckwheat which provides vitamins B1 and B2, several minerals, and nearly twice the amount of proteins found in rice. It also contains great quantities of Rutin, a bioflavonoid that includes the catechins of green tea and the polyphenols of red wine, which is not found in other grains or beans. This bioflavonoid strengthens capillaries, helping people suffering from arteriosclerosis and high blood pressure. Recent studies indicate that rutin is also a powerful antioxidant that fights free radicals, which are responsible for many cancers. Health benefits of buckwheat: Decreases cholesterol

Lowers blood pressure

Reduces fat accumulation

Promotes healthy bowel movements

Fits a well-balanced and low-calorie diet

The Japanese version of these noodles, donguri-men (Japanese:どんぐり), typically has less acorn flour than the original Korean version. The raw noodles are slightly coarser in cut and texture and more brittle than standard buckwheat soba noodles. Cooked acorn soba noodles are nuttier in flavor, healthier, and slightly saltier than buckwheat noodles. Particulary they contain many antioxidants and may be considered an adaptogenic (anti-cancerous) food.

Differences Between Starch and Flour Bases

A common problem among Korean-manufactured products is that their ingredient labels are often not properly translated. Acorn starch is frequently mislabeled as acorn flour or acorn powder. In reality, acorn starch is essentially highly-refined acorn flour, devoid of fiber, fat, and almost all nutrition. While the acorn itself does indeed contain acorn starch, that starch is not highly-refined. Acorn starch, in contrast, is extracted from the meat of the kernel using a wet process and then dehydrated. The heart, or germ, of the kernel is removed and used for producing acorn oil, which is comparable in flavor and quality to olive oil. The hull is separated from the kernel meat, and the starch is extracted from the kernel meat. It might be more accurate to use the term “acorn meal”, although a meal is a coarser, less refined version of flour.

Marketing and Product Availability

Both flour and starch-based acorn noodles are available in upscale Korean markets. A few Japanese markets also carry acorn soba noodles, but in general, acorn soba noodles are difficult to find. Acorn soba noodles are very widespread within a niche Korean health-orientated community, many of whom are also 7th day Adventists, a religious organization that values healthy, vegetarian cuisine. Acorn soba noodles have not been available to the wider public until the advent of Acorn Hut, the online organic Asian food store.
