Glutinous rice

Glutinous rice (Oryza sativa var. glutinosa or Oryza glutinosa; also called sticky rice, sweet rice, waxy rice, botan rice, biroin chal, mochi rice, and pearl rice) is a type of short-grained Asian rice that is especially sticky when cooked. It is called glutinous (< Latin glūtinōsus) in the sense of being glue-like or sticky and not in the sense of containing gluten; on the other hand, it is called sticky but should not be confused with the other varieties of Asian rice that become sticky to one degree or another when cooked.

Cultivation

Glutinous rice is a type of rice grown in Laos, Myanmar, Vietnam, Bangladesh, China, Japan, Korea, Philippines, Thailand, Taiwan, Cambodia and Indonesia. An estimated 85% of Laotian rice production is of this type. Records of this rice go back at least 1,100 years, in this region. The improved rice varieties that swept through Asia during the Green Revolution were non-glutinous and Laotian farmers rejected them in favor of their traditional sticky varieties. Over time, higher-yield strains of glutinous rice have become available from the Laotian National Rice Research Programme. By 1999, more than 70% of the area along the Mekong River Valley were of these newer strains. In China, glutinous rice has been grown for at least 2,000 years. According to legend, it was used to make the mortar in the construction of the Great Wall of China, and chemical tests have confirmed that this is true for the city walls of Xian. It is used in recipes throughout Southeast and East Asia.

Constituents

Glutinous rice does not contain dietary gluten (i.e. does not contain glutenin and gliadin), and thus should be safe for gluten-free diets. What distinguishes it from other types of rice is having no (or negligible amounts of) amylose, and high amounts of amylopectin (those are the two components of starch). Amylopectin is responsible for the sticky quality of glutinous rice. The difference has been traced to a single mutation that was selected for by farmers.

Glutinous rice can be used either milled or unmilled (that is, with the bran removed or not removed). Milled rice is white in color, whereas the bran can give unmilled glutinous rice a purple or black color. However, black and purple glutinous rice are distinct strains from white glutinous rice, and in developing Asia, there is little regulation, resulting in many advisories about toxic dyes added to color adulterated rice. Both black and white glutinous rice can be cooked as grains or ground into flour and cooked as a paste or gel.

Burmese traditions

Glutinous rice, called kao hnyin (), is very popular in Myanmar (also known as Burma). Kao hnyin baung () is a breakfast dish with boiled peas (pèbyouk) or with a variety of fritters such as urad dal (baya gyaw) served on a banana leaf. It may actually be cooked wrapped in a banana leaf, often with peas, and served with a sprinkle of salted toasted sesame and often grated coconut. The purple variety known as kao hynin ngacheik () is equally popular cooked as ngacheik paung.

They may both be cooked and pounded into cakes with sesame called hkaw bouk, another favourite version in the north among the Shan and the Kachin and served grilled or fried.

Htamanè pwè (festival) takes place on the full moon of Dabodwè (February) when htamanè is cooked in a huge wok, requiring two men each with a wooden spoon the size of an oar and a third man coordinating the action of folding and stirring the contents, which include kao hnyin, ngacheik, coconut shavings, peanuts, sesame and ginger in peanut oil.

Si htamin () is glutinous rice cooked with turmeric and onions in peanut oil, and served with toasted sesame and crisp fried onions, a popular breakfast like kao hnyin baung and ngacheik paung. Paung din () is another ready-to-eat portable form cooked in a segment of bamboo, and when the bamboo is peeled off, it retains a thin skin around giving off at the same time a distinctive aroma. This is also sold by street vendors in Thailand, where it is known as 'khao lam'. Mont let kauk () is made from glutinous rice flour, donut-shaped and fried like baya gyaw, but eaten with a dip of jaggery or palm sugar syrup. Mont lone yei baw () are glutinous rice balls with jaggery inside thrown into boiling water in a huge wok and ready to serve as soon as they resurface - a time-honoured tradition during Thingyan, the Burmese New Year festival. Htoe mont (), glutinous rice cake with raisins, cashews and coconut shavings, is a traditional dessert for special occasions and very much appreciated as a present from Mandalay.

Nga pyaw douk, banana in glutinous rice wrapped in banana leaf and steamed and served with grated coconut - another favourite snack sold by street hawkers like kao hnyin baung and mont let kauk.

Chinese traditions

In Chinese, glutinous rice is known as nuòmǐ (糯米).

The Chinese dish, nuòmǐ fàn (糯米飯), is steamed glutinous rice usually cooked with Chinese sausage, chopped Chinese mushrooms, chopped barbecue pork and optionally dried shrimp or scallop (recipe varies depending on the cook's preference).

Zongzi (Traditional Chinese 糭子/糉子, Simplified Chinese 粽子) is a Chinese dumpling consisting of glutinous rice and sweet or savory fillings wrapped in leaves which is then boiled or steamed, commonly eaten during the Dragon Boat Festival. Lo mai gai is a parcel of glutinous rice and chicken wrapped in lotus leaves and steamed. It is served as a dim sum dish in Hong Kong, Singapore, and Malaysia. Ba bao fan (八寶飯) or "eight treasure rice" is a dessert made from glutinous rice steamed and mixed with lard, sugar, and eight kinds of fruits or nuts.

Glutinous rice is also often ground to make glutinous rice flour. This flour is then made into niangao and sweet filled dumplings tangyuan, both of which are commonly eaten at Chinese New Year. It also sometimes used as a thickener and for baking.

Filipino traditions

In the Philippines, glutinous rice is known as malagkit (literally "sticky" in Tagalog, cognate to Malay melekit), milled glutinous rice is known as galapong. Milling - that is, washing and soaking the rice first, and then proceeding to milling proper - is generally preferred as this removes the unpleasant powdery texture found in glutinous rice which has been dried first and then converted to flour.

Glutinous rice cooked in coconut or banana leaf wrappers are steamed to produce suman, of which there are many varieties depending on the region. Some of the common toppings are bukayo, grated mature coconut cooked in sugar, coconut jam, and freshly grated coconut. Some regions eat suman as a snack with ripe mangoes or bananas. In suman sa lihiya (lye), the rice grains are treated with a solution of lye and then dried, then the grains are poured into a banana leaf cone or coconut leaf wrapper and steamed. It may be mixed with sugar, coconut milk, or other grains such as millet.

Malagkit is also used in puto, or steamed rice dumplings, of which numerous variations exist.

A general term for sweet rice cake, bibingka mainly consists of glutinous rice cooked with coconut milk. Bibingka is often associated with the Philippine Christmas season. In tandem with the bibingka's role in Philippine Christmas tradition is the puto bumbong - a suman-like sweet dish steamed in special containers with bamboo tubes, and served with butter, grated coconuts, sugar, and sometimes toasted sesame seeds. Puto bumbong traditionally uses a special heirloom variety of glutinous rice called pirurutong, which has a naturally purple colour.

Another traditional Filipino snack very similar to Japanese mochi is called palitao.

Glutinous rice is also used in gruel-like dishes such as champorado, which is cooked with cocoa powder and sweetened. Milk is usually added, and tuyo is served with it as a counterpoint. Lugaw, goto, arroz caldo, are all variants of rice porridge dishes featuring glutinous rice mixed with normal rice.

Bilo-bilo is another dish that uses glutinous rice. It is a sweet, thick soup that has coconut milk, jackfruit, sweet potatoes, plantain, sago pearls, and the bilo - or galapong shaped into gummy balls.

Japanese traditions

In Japan, glutinous rice is known as mochigome (). Prepared as rice flour, it is known as mochiko. It is used to make mochi, a traditional rice cake prepared for the Japanese New Year but also eaten year-round. See also Japanese rice.

Korean traditions

In Korea, glutinous rice is called chapssal (Hangul: 찹쌀), and its characteristic stickiness is called chalgi (Hangul: 찰기). Cooked rice made of glutinous rice is called chalbap (Hangul: 찰밥) and rice cakes (Hangul: 떡, ddeok) are called chalddeok or chapssalddeok (Hangul: 찰떡, 찹쌀떡). Chalbap is used as stuffing in samgyetang (Hangul: 삼계탕).

Laotian traditions

Glutinous rice is the main rice eaten in Laos, where it is known as khao niao (Lao: ): "khao" means rice, and "niao" means sticky. It is cooked by soaking for several hours and then steaming in a bamboo pot or huat (Lao: ຫວດ, Thai: หวด). After that, it should be turned out on a clean surface and kneaded with a wooden paddle to release the steam; this results in rice balls that will stick to themselves but not to fingers. The large rice ball is kept in a small basket made of bamboo or katip (Lao: ກະຕິບ, Thai: กระติบ). The rice is sticky but dry, rather than wet and gummy like nonglutinous varieties. The fingers of the right hand are used to eat it by wadding the rice.

Laotians consume glutinous rice as part of their main diet and they also use toasted glutinous rice (khao kua) to add a nut-like flavor to many dishes.

A popular Laotian meal is a combination of Laotian grilled chicken (ping gai), Laotian papaya salad (tam mak hoong), and Laotian sticky rice (khao niao).

Khao niao is also used as an ingredient in desserts. Khao niao mixed with coconut milk can be served with ripened mango or durian. Khao tom is a steamed mixture of khao niao with sliced fruits and coconut milk.

Malay and Indonesian traditions

In Singapore and Malaysia, glutinous rice is known as pulut, and in Indonesia it is known as ketan. It is usually mixed with santan, meaning coconut milk in Malay, along with a bit of salt to add some taste. It is widely used during the Raya festive seasons as traditional food, such as Palas - cooked pulut wrapped in triangular shaped crafts made from local leaves and left to be boiled for 3 – 4 hours to result nice shaped compression and to bring out the aroma or taste from the wrapped leaves.

Lemang - wrapped in banana leaves and inside a bamboo, and left to be barbecued/grilled on an open fire, to make the taste and texture tender and unique

Ketupat - square shaped crafts made from the same local leaves as palas, but it is usually filled with regular rice grains instead of pulut, but it depends on the maker.

Kue Lupis - glutinous rice wrapped in individual triangles using banana leaves and left to boil for a few hours. The rice pieces are then tossed with grated coconut all over and served with palm sugar syrup.

Pulut will also be used in certain famous kuih, traditional local desserts.

Thai traditions

Similar to Laos, glutinous rice is also known as khao niao (; Lanna: เข้าหนึ้ง, khao nueng). Northern Thais (Lanna people) and northeastern Thais (Isan people), as most other Tai peoples except Central and Southern Thais, traditionally eat glutinous rice as their staple food. Glutinous rice is also used as the basis for the brewing of sato (), an alcoholic beverage also known as "Thai rice wine". Famous in Thai cuisine is khao niao mamuang (): Thai sweet coconut sticky rice with mango.
