Hot Rice – Just Add Cold Water

Hot Rice

I saw this on Boing Boing and thought I’d post it cause it’s pretty damn cool. Apparently Japanese scientists can do just about anything, including turning your cold tap water into piping hot water able to cook rice.

An environmental consulting firm and other developers here have come up with a non-perishable food pack that creates steaming hot rice with the simple addition of cold water.

The group has recently introduced the product, named “Hotto! Raisu,” to the market.

By subjecting rice to 4,000 times normal atmospheric pressure, the developers were able to preserve rice for long periods in a soft form that holds moisture. When water is poured over an exothermic agent in the pack, steam warms the rice contained within, and after about 15 minutes, the dish is piping hot.

Officials say the product could be useful in areas that have been hit by natural disasters, when electricity is often unavailable. The product is not cheap, costing 10,000 yen for 30 packs with pickled ume plums, but its producers say they are ready to work on new ideas.

“If our sales increase, we want to work at developing new side dishes,” one official said.

And according to yumsugar, right now the product is decently priced, (10,000 yen for 30 packs, or approximately $85 for 30), but I don’t know if that’s cheap enough to be ideal for natural disaster zones. Either way it’s still absolutely awesome.

I agree.

    i don’t think this is a new…maybe for cooking rice, but they have pouches that heat food up by usig water, too. Awesome idea though…i want like 50 boxes.

    You might be right. Does sound a little familiar, but I can’t name anything that heats up like that of the top of my head. I’ll be on the lookout, though.

    Military “Meals Ready to Eat” (the famous MREs) use technology like this for the heating pack, and have for years. The difference is you don’t pour the water on the food itself in the MRE.

    Ah…thanks for clearing that up. Yeah, I thought there was something different about this rice thing.

    It is kind a of cool invention though. I bet the rice tastes infinitely better than MREs. LOL.
