Onigiri (お握り or 御握り), also known as omusubi (お結び) or nigirimeshi (握り飯), is a Japanese rice ball made from white rice. It is usually formed into triangular or cylindrical shapes, and wrapped in nori (seaweed). Onigiri traditionally have sour or salty fillings such as umeboshi (pickled Chinese plum), salted salmon, katsuobushi (smoked and fermented bonito), kombu, tarako or mentaiko (pollock roe), or takanazuke (pickled Japanese giant red mustard greens). Because it is easily portable and eaten by hand, onigiri has been used as portable food or bento from ancient times to the present day. Originally, it was used as a way to use and store left-over rice, but it later became a regular meal. Many Japanese convenience stores and supermarkets stock onigiri with various fillings and flavors. It has become so mainstream that it is even served in izakayas and sit-down restaurants. There are even specialized shops which only sell onigiri to take out. Due to the popularity of this trend in Japan, onigiri has become a popular staple in Japanese restaurants worldwide.

Onigiri is not a form of sushi and should not be confused with the type of sushi called nigirizushi or simply nigiri. Onigiri is made with plain rice (sometimes lightly salted), while sushi is made of rice with vinegar, sugar and salt. Onigiri makes rice portable and easy to eat as well as preserving it, while sushi originated as a way of preserving fish.

History

Prehistoric

On November 12, 1987, lumps of carbonized grains of rice, thought to be riceballs, were excavated from a building belonging to the Yayoi period (2000 years ago) in the Sugitani Chanobatake Ruins in Ishikawa Prefecture. The carbonized rice had traces which revealed that it was formed by human hands, thus it was initially documented as “the oldest onigiri.” In subsequent research, it was thought to be steamed and grilled, rather than boiled like today’s rice, similar to another dish called chimaki. Since then, it has been academically called the “chimaki-shaped carbonized rice lumps (チマキ状炭化米塊)”.

Pre-Modern

Before the use of chopsticks became widespread, in the Nara period, rice was often rolled into a small ball so that it could be easily picked up. In the Heian period, rice was made into small rectangular shapes known as tonjiki so that they could be piled onto a plate and easily eaten. At that time, onigiri were called tonjiki and often consumed at outdoor picnic lunches

Modern

In the 1980s, a machine to make triangular onigiri was invented. Rather than rolling the filling inside, the flavoring was put into a hole in the onigiri and the hole was hidden by nori. Since the onigiri made by this machine came with nori already applied to the rice ball, over time the nori became moist and sticky, clinging to the rice.

A packaging improvement allowed the nori to be stored separately from the rice. Before eating, the diner could open the packet of nori and wrap the onigiri. The use of a hole for filling the onigiri made new flavors of onigiri easier to produce as this cooking process did not require changes from ingredient to ingredient. Modern mechanically wrapped onigiri are specially folded so that the plastic wrapping is between the nori and rice to act as a moisture barrier. When the packaging is pulled open at both ends, the nori and rice come into contact and are eaten together. This packaging is commonly found for both triangular onigiri and rolls (細巻き).

Rice and shapes

Usually, onigiri is made with boiled white rice, though it is sometimes made with different varieties of cooked rice, such as:

-Okowa or kowa-meshi: glutinous rice cooked or steamed with vegetables

-Sekihan: rice cooked with red azuki beans

-Maze-gohan: rice cooked with various preferred ingredients

-Fried rice

-Brown rice

The rice may be seasoned with salt, sesame, furikake, dried shiso flakes, and so on.

    Almost forgot that the last match week of Serie A was on today and I’m watching Napoli-Cagliari. Just saw someone flying what looked like a big Confederate Flag in the crowd. Apparently this is something that Napoli fans do because they don’t like how they’re treated by Northern Italians… Umm, pretty sure they could have found a better way to symbolize thatfidel-wut

    Isn’t walking supposed to be calming? I always finish my walks bugged by everything that’s on my mind. Without fail.

    I’ve always heard that walking is supposed to clear your head and I usually am more stressed after a walk

    If no dirt is found on Elias being an antisemite, I hope to god he sues these fucks for slandering him as one and lives a good life in prison (I doubt reality will end up like that tho), But this case I think will be important in how the legal system will classify antizionism with antisemitism which is also pretty scary

      Wasn’t there already a law passed in Congress this past year that stated that antizionism would count as antisemitism? There’s a reason why the term is already used so interchangeably by all these fucking ghouls in government and the mainstream media.

        This made me think ofnwhether Tolkien ever referred to distilled liquor. Seems too modern for him and then I remembered the Brandywine river. Turns out there’s a whole explanation there and it seems that distilled booze isn’t a thing in Arda

        From Tolkien Gateway:

        The Hobbits of the Shire originally gave it the punning name Branda-nîn, meaning “border water” in original Hobbitish Westron. This was later punned again as Bralda-hîm meaning “heady ale” (referring to the colour of its water), which Tolkien renders into English as Brandywine.[4]

        The word Brandywine both resembles the original Elvish name Baranduin, and provides the Hobbitish meaning adequately.

        The word brandywine was actually the archaic English word for brandy as imported from the Dutch brandewijn. David Salo noted that it represents a possible Old English *baernedwin, meaning “burned wine”, which would resemble quite closely the original Elvish Baranduin,[5] making Hobbitish Brandywine a legitimate corruption of S. Baranduin."

          I feel like it’d be a thing but it’d have to be like a Mordor/southern thing, people who have been exposed to some form of industry, since you’d need that sort of background for distillation to become apparent

          so like there’s probably liquor but it’s probably like shit moonshine whatever humans living in the periphery of Mordor’s heavy industry manage to figure out

            It’s easy enough to imagine but there’s no textual evidence. I could also see the Numenoreans getting into distilling but without any solid mention the safest assumption is that it’s not there. If the Anglo Saxxons didn’t have it he probably didn’t want it in middle earth either.

    I fuckin hate being so angry sometimes, it’s embarassing to lose control of and I immediately think about Palestine again and have it put into perspective for me that I am shamefully lacking in emotional fortitude and would have my psyche shredded by the evil being inflicted there. To the point that even comparing the two feels like a bad joke, but I can’t stop comparing it with…everything. This genocide is a hideous black hole devouring all horizons and my thoughts can never escape it’s gravity for long.
