The amylopectin details may be right, but the rest is wrong. Conbini's sell brown rice onigiri (look for 玄米), it's just usually a very limited selection. They don't fall apart, and you eat them the same as normal onigiri.
After posting this comment I then decided to look into it (in my usual way) and just looking for homemade brown rice onigiri what I found was that at least the couple of recipes I looked at used short grain brown rice (which I did not even realize existed) and/or recommended using more water than usual.
Whole Foods carries a store brand short grain brown rice at a reasonable price that I really like. It’s one of my go-to rices and essentially the only thing I go to Whole Foods for, as I haven’t found a comparable product or price point elsewhere. I think it’s about $2.50/lb these days.
I just finished some tonight, and I’m certain it’s sticky enough to hold its shape.
Yup, if you want to do it at home, make it a little bit mushier. I don't like it, but it is very doable. Commercially they may use a binder, I don't know, I just wanted to make sure people knew they're available!
I did it tonight and when i picked up the rice i used wet fingers to give it just a touch more binding ability. Worked well. Kids loved it. Am excited to eat the brown rice onigiri tomorrow.
There is no white rice plant. It's all brown rice with the bran removed. Brown short grain rice doesn't have different starches than the same rice without its bran.
Diabetes scales with obesity and age. Japan has a very old population, but less obesity than the US. White rice despite its glycemic index is not super high calorie. If it's a contributing favor, it's because of weight-gain, not glycemic index.
There are also other food items which have versions that are black in colour, some of which could be not naturally, but by processing them in some way, for example, black garlic.
It’s the Japanese equivalent of “cup” as a measurement unit, and at 180 ml is about 76% of a US cup. Japanese rice cookers are marked and filled in units of gō. You put n gō of uncooked rice in it, and then fill water up to the n mark. One gō is roughly 150 grams of uncooked rice, which amounts to around 530 kcal. Traditionally, a wooden box was used to measure one gō: https://commons.wikimedia.org/wiki/File:Masu,_One-Gō_measure...
A Japanese measuring unit for rice, kind of analogous to "one cup" in US kitchens. Measuring cups distributed with rice cookers are usually one gō in volume even in the US.
