This Fall’s featured ingredient is Rice.

Rice is the edible seed or grain of the Oryza grass.

Rice is the most widely consumed staple food of the world’s human population.

There are many varieties of rice.  Grains can be short, medium or long.  Some are sticky when cooked due being rich in carbohydrate amylopectin.  Other rice varieties mainly contain amylose making the grains stay separate.

Rice grows in an array of colors including brown, white, red, yellow, black and even bright purple.  Some rice manufacturers add bamboo juice to rice for increased nutritional value, turning it green.

Rice is used to make many food products, including vinegars, flour, cakes, noodles, crackers, bread, soup, milk, ice cream, and candies.

The majority of rice is grown in the Asian countries of China, India, Indonesia, Bangladesh, Vietnam, Thailand, Myanmar, Pakistan, Philippines, Korea and Japan.  1

Rice is believed to have been originally domesticated around 10,000 years ago in the Pearl River valley region of China.  2

From East Asia, domesticated rice was spread to the rest of Asia, and then to Europe.  European colonialists brought rice to Africa and the Americas.

Around the beginning of the 18th century, rice began being grown by US Southerners, using African slaves’ labor and knowledge about its cultivation.  After the abolishment of slavery and rice production became less profitable, it soon died out in the south.  Currently there is a movement reintroducing prized southern strains of rice, such as “Carolina Gold,” as commercial crops.  3

Rice cultivation began in California during the Gold Rush by Chinese immigrant laborers growing small amounts of the grain for their own consumption.  California commercial production later began as southern US production died out, in the early 20th century.

Calrose rice is a medium grain rice, developed by the University of California, which became the founding variety of the California rice industry.  It began being grown in the late 1940s.  It is still commonly used to prepare Japanese cuisine in North America, including sushi and rice balls, due to its soft and sticky texture.  4

Festivals are held all over the world to celebrate rice planting and harvest.  The Japanese holiday, Niiname-sai, celebrated the autumn rice harvest.  The emperor would thank nature for the year’s harvest, and the new rice would be prepared for the first time.  Then everyone joined in a feast with dancing and singing.

In Japan, the most popular kind of rice is short grain rice.  Because the rice is sticky, it can be formed into shapes and decorated.  These Japanese rice balls are called onigiri, literally translated as “grip” or holdable rice.  They are traditionally made from white rice formed into shapes and often filled with a salty or sour ingredient, such as ume plum, meat, or seafood, as a natural preservative.  5

Before chopsticks began being used in Japan, rice was often rolled into balls so it could be easily picked up and eaten.  It is said that samurai warriors carried rice balls with them into battle as a quick snack.  Later they became a favorite dish at picnics and in lunches boxes.

Today, many Japanese carefully prepare a special lunch box for their spouse, child, or themselves called a bento.  Character bentos or kyaraben are lunches decorated to look like characters from cartoons, comic books or video games.  Picture bentos or oekakiben are decorated to look like scenes from nature or cities, people, and animals.

Usually parents make bentos for their children, but many schools are now celebrating a “Bento Day.”  On “Bento Day” children design and prepare their own bentos to bring to school, inspiring creativity and appreciation for all the hard work it requires.  6

White rice is a rich source of carbohydrates, and protein.  When combined with legumes, nuts or seeds, all essential amino acids are provided.  Whole grain brown rice, which still has the bran and germ intact, also contains B-vitamins, iron, magnesium, healthy fats and fiber.  7

This Fall’s Featured Recipe is for Onigiri Rice Balls.  Choose a short or medium grain rice with a sticky texture, suitable for sushi, so the rice can be formed into shapes.  In Japan, this kind of rice is called hakumai.  (Not to be confused with glutinous sticky mochigome rice, used for making rice “cakes.”)  We chose California Calrose rice.  Short-grain sticky brown rice can also be used, and has a delicious nutty flavor.

Below are some suggestions of colorful decorations for one’s creations, but any food one enjoys could be used.  Rice balls can be as simple as plain rice or elaborate as Halloween monsters and wild animals with flavorful fillings.  The mighty internet has thousands of photos for inspiration.

Tip:  Water (and other liquids) takes away the stickiness of rice.  This can be used to one’s advantage by lightly wetting one’s hands before beginning to shape the rice.  But too much water will make the rice creations fall apart.  Refrigeration will also decrease the stickiness of rice, and make it harden.  Rice balls are best eaten fresh.
