Over the past year or two I have become pretty successful at cooking rice Japanese style, at home on the stove, as recommended by Keiichi-san in a post on the Tenkara-fisher forum.
( I think the key steps are: a) don’t use to much water, about 1:1 ratio, depending on type of rice , b) soak the rice for 30 - 60 minutes before cooking it)
However, the above video is intended to show how to cook rice in a mess kit or Hangou (ハンゴウ/ 飯盒). Good for when carrying your cooking kit.
But a hangou is thin metal. I think the rice actually cooks much better in a pot with thick metal bottom…
Steaming rice below a wood fire is an interesting method I was not familiar with.
Seems to be similar to the method shown in this video. Where she steams the rice in a plastic bag.
However, I think steaming the rice in a damp towel (tenugui / てぬぐい) in soft sand or gravel, below a stone, with wood fire on top - would be easier than in the hard ground as shown in this video. She certainly did not need many tools to cook her rice.
You mentioned using Miso Seasoning. If you like Miso (味噌) I found this interesting rice variation that would match well if you already have a wood fire going.
This past winter in February I went on a ski trip to Akita Prefecture. We stayed at a lodge テレマーク山荘森吉山 The okami-san at the lodge made us きりたんぽ (minus the miso) the first night. First time I had whale was there too. They were delicious https://photos.app.goo.gl/MkPhAAyHS3ijQy0D3 I LOVE Japanese food
While this video is a little silly (in my opinion, at least), I do think the translation is good and shows how to cook rice with a hango (or mess kit as they translate it) over a campfire. Not to mention, make it look easy.
Although, the Japanese sounds like it is either being read by a computer or someone who doesn’t know Japanese very well.
For those like me, who think in Cups and do not think in X cc,
let’s see, how many cups is 540cc anyway?
The key to remember is [１合ご飯] 1-Gō rice = 180cc rice = ~ 3/4 cups. Making 1 cup about 240cc.
And 1-Gō rice (uncooked) is supposed to make the correct amount of cooked rice for 1 person. Though it is more than I can eat at one meal. So, let’s seen now 540 cc is 2 1/4 cups = 3-Gō [3合]
And that is why if you buy a rice cooker, such as a Zojirushi model, it may come with a little measuring cup that is the size of 1 Gō.
I thought the 飯ごうでご飯を炊こう, In a Hangō let’s cook rice, video was pretty good.
I am a little surprised I don’t recall seeing it before.
