Bamboo Shoot

Bamboo shoots or bamboo sprouts are the edible shoots (new bamboo culms that come out of the ground) of many bamboo species including '' Bambusa vulgaris'' and '' Phyllostachys edulis''. They are used as vegetables in numerous Asian dishes and broths. They are sold in various processed shapes and are available in fresh, dried, and canned versions.

Raw bamboo shoots contain cyanogenic glycosides, natural toxins also contained in cassava. The toxins must be destroyed by thorough cooking, and for this reason, fresh bamboo shoots are boiled before being used in other ways. The toxins are also destroyed in the canning process.

Freshly collected bamboo shoots are a good source of thiamine, niacin, vitamin A, vitamin B6, and vitamin E. 17 different amino acids have been reported, 8 of them essential for humans. The amount of amino acids in canned and fermented shoots is lower than when freshly prepared.

Uses

Culinary

Raw bamboo is toxic to humans, containing cyanide compounds, hence it is always boiled when used for human consumption. The diet of giant pandas and red pandas is largely made up of raw bamboo; the animals' body tissue is not well able to detoxify cyanide, but their gut microbiomes are significantly enriched in putative genes coding for enzymes related to cyanide degradation, suggesting that they have cyanide-digesting gut microbes.

East Asia

In certain parts of Japan, China, and Taiwan, shoots from the giant timber bamboo ''Bambusa oldhamii'' are harvested in spring or early summer. Young shoots from this species are highly sought-after due to their crisp texture and sweet taste. Older shoots, however, have an acrid flavor and should be sliced thin and boiled in a large volume of water several times. The sliced bamboo is edible after boiling. ''B. oldhamii'' is more widely known as a noninvasive landscaping bamboo.

Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots. In Japan, '' menma'' is a common topping for ramen noodle soup. In China, luosifen river snail noodles, a popular dish from Guangxi, get their famously pungent smell from pickled bamboo shoots.

South Asia

In Nepal, they are used in dishes that have been well known in the country for centuries. A popular dish is ''tama'' (fermented bamboo shoot), made with potato and beans. An old popular song in Nepali mentions ''tama'' as "my mother loves vegetable of recipe containing potato, beans, and ''tama''". Some varieties of bamboo shoots commonly grown in the Sikkim Himalayas of India are '' Dendrocalamus hamiltonii'', '' Dendrocalamus sikkimensis'' and '' Bambusa tulda'' locally known as ''choya bans'', ''bhalu bans'' and ''karati bans''. These are edible when young. These bamboo shoots are collected, defoliated and boiled in water with turmeric powder for 10–15 minutes to remove the bitter taste of the bamboo after which the ''tama'' is ready for consumption. ''Tama'' is commonly sold in local markets during the months of June to September when young bamboo shoots sprout.

In Assam, bamboo shoot is called ''bah gaj'' in Assamese and ''hen-up'' in Karbi. It is an integral part of traditional Assamese cuisine. Fermented bamboo shoot, called ''khorisa,'' is a widely used ingredient in Assamese recipes for meats such as pork, chicken, duck and squab or pigeon. Fermentation increases the nutritional value of bamboo shoots by making some nutrients more bioavailable and degrading toxins.

In Karnataka, Andhra Pradesh, and Northern Tamilnadu, the bamboo shoots are used as a special dish during the monsoons (due to seasonal availability). It is common in Tulunadu and Malnad regions. It goes by the name ''kanile'' or kalale'' in Tulu, ''Veduru Kommulu'' in Telugu, and ''Moongil Kuruthu'' in Tamil. The shoots are usually sliced and soaked in water for two to three days, after which the water is drained and replenished each day to extricate and remove toxins. It is also used as a pickle. It is consumed as a delicacy by all communities in the region.

In the Diyun region of Arunachal Pradesh, the Chakma people call them ''bashchuri''. The fermented version is called ''medukkeye'' and is often served fried with pork. The bamboo shoots can also be fermented and stored with vinegar.

In Jharkhand, India, the bamboo shoots are used as a vegetable. Young shoots and stored shoots are known as ''karil'' and ''shandhna'' respectively.

In the western part of Odisha, India, they are known as ''karadi'' and are used in traditional curries such as Ambila, pithou bhaja and pickle. In monsoon, it can be abundantly found in Bamboo forest of Karlapat wildlife sanctuary and mostly prepared in homes using mustard paste. They can be stored for months in an air tight container. They are also dried in sun increasing their shelf life and these dried shoots are called ''Hendua''. The dried shoots are used in curries of roasted fish, called ''Poda Macha''.

In Nagaland, India, bamboo shoots are both cooked and eaten as a fresh food item or fermented for a variety of culinary uses. Fermented bamboo shoot is commonly known as ''bas tenga''. Cooking pork with a generous portion of fermented bamboo shoot is very popular in Naga cuisine.

In Manipur, India, they are known as ''u-soi''. They are also fermented and preserved after which they are known as ''soibum''. They are used in a wide variety of dishes – among which are ''iromba, ooti'' and ''kangshu etc.'' The fermented bamboo shoot which is preserved for many months is known as ''soijin''. ''Soijin'' can be stored up to 10 years in Andro village. Generally, ''soijin'' or ''usoi'' is in a big basket made of bamboo. However, they are stored in earthen pot in Andro village.

In Meghalaya, bamboo shoots are either used fresh or fermented and made into pickles, soups with pork or dried fish, or curried and seasoned with sesame seeds or made into a sauce with fermented fish. It sometimes cooked along with yam leaves and dried fish.

In Chittagong Hill Tracts, Bangladesh, bamboo shoots are a traditional food of the indigenous Jumma people. The preparation of their dishes consist of several steps. First, bamboo shoots are collected from the bamboo forest then defoliated and boiled in water. Afterwards, the bamboo shoot is prepared with shrimp paste, chili, garlic paste, and salt.

Southeast Asia

In the Philippines, bamboo shoots are primarily harvested from bolo bamboo (''Gigantochloa levis''), giant bamboo ('' Dendrocalamus asper''), common bamboo ('' Bambusa vulgaris''), spiny bamboo ('' Bambusa blumeana''), and two endemic species, bayog (''Bambusa merrilliana'') and laak (''Bambusa philippinensis''). Other economically important species also harvested for bamboo shoots include kayali ('' Gigantochloa atter''), male bamboo ('' Dendrocalamus strictus''), and climbing bamboos ('' Dinochloa'' spp.) Another endemic species, the lumampao or bagakay bamboo (''Schizostachyum lumampao''), which are used for making '' sawali'' (woven bamboo strips), are also occasionally harvested for bamboo shoots. In Filipino cuisine, the shoots are commonly called ''labóng'' (other names include ''rabong'', ''dabong'', or ''tambo''). The two most popular dishes for these are '' ginataáng labóng'' (shoots in coconut milk and chilies) and '' dinengdeng na labóng'' (shoots in fish '' bagoóng'' and stew of string beans, '' saluyot'', and '' tinapa''). They are also sautéed alone or with other ingredients as in '' paklay'', or cooked as fried or fresh ''lumpia''. Bamboo shoots are also preserved as '' atchara'', traditional sweet pickles that are often made from papaya.

In Thai cuisine bamboo shoots are called ''no mai''. It can be used in stir-fries, soups such as '' tom kha kai'', curries such as '' kaeng tai pla'', as well as in salads such as '' sup no-mai''. Some dishes ask for fresh bamboo shoots, others for pickled bamboo shoots (''no mai dong'').

In Vietnamese cuisine, shredded bamboo shoots are used alone or with other vegetable in many stir-fried vegetable dishes. It may also be used as the sole vegetable ingredient in pork chop soup. Duck and bamboo shoot noodles (''Bún măng vịt'') is also a famous noodle dish in Vietnam.

In Myanmar, bamboo shoots are called ''hmyit'' (). They can be used in a soup called ''myahait hcaut tar la bot'' or talabaw, bamboo soup. The preparation of this dish generally follows three steps. First, the bamboo shoots are collected from a bamboo forest. Bamboo can be found in the whole of Myanmar but the bamboo shoots from the two northernmost regions (Kachin State and Sagaing Region) are soft and good in taste. The bamboo shoots are then boiled in water after which they can be cooked with curry powder, rice powder, and other ingredients such as snakehead fish and basil leaves. A small amount of rice and some shreds of meat or seafood may also be added. The soup was traditionally used by the Karen people as a supplement to rice, which was not readily or cheaply available to them. Talabaw is one of the most well known soups in Myanmar, and widely considered to be the essential dish of Karen cuisine. Another bamboo shoot dish in Burmese cuisine is a sour bamboo shoot curry called ''hmyit chin hin'' (မျှစ်ချဉ်ဟင်း), a specialty of Naypyidaw in central Burma.

In Indonesia, they are sliced thinly to be boiled with coconut milk and spices to make ''gulai rebung''. Other recipes using bamboo shoots are '' sayur lodeh'' (mixed vegetables in coconut milk) and ''lun pia'' (sometimes written ''lumpia'': fried wrapped bamboo shoots with vegetables). The shoots of some species contain cyanide that must be leached or boiled out before they can be eaten safely. Slicing the bamboo shoots thinly assists in this leaching.

Ethiopia

Bamboo shoots are also eaten in Ethiopia. The locations where bamboo grows are not contiguous. Bamboo shoots of ''O. abyssinica'' are eaten in lowland locations of Pawe, Assosa and Bambasi districts of Benishangul Gumuz Regional State and in Sinan Wereda of Amhara Regional State.Feleke, Sisay. "Site factor on nutritional content of Arundinaria alpina and Oxytenanthera abyssinica bamboo shoots in Ethiopia." ''Journal of Horticulture and Forestry'' 5, no. 8 (2013): 115-121.

Bamboo shoots of ''A. alpina'' are also eaten in higher elevations, including from two bamboo forests about 80 km. apart, both areas at higher elevations than the surrounding land.Embaye, Kassahun. "The indigenous bamboo forests of Ethiopia: an overview." ''AMBIO: A Journal of the Human Environment'' 29, no. 8 (2000): 518-521. One is on a mountain south of Mizan Teferi, the other is on the higher elevations near Maasha, between the cities of Tepi and Gore.
