Unlike other pots, the innovative “Kuru-Kuru Nabe” pot, invented by Japanese dentist Hideki Watanabe, creates a whirpool motion via thermodynamics that stirs whatever is placed inside when the liquid starts heating up. Compacting foam was added to the sides to lessen the chance of its contents boiling over. Continue reading for a video and more information.
As you can see, the inertia of the moving water results in more efficient heating of the pot’s contents so the water’s boiling point is reached in a shorter time, thus saving energy. As well, the spinning water tends to rise higher along the sides of the pot, channeling pasta or other foods into the center of the pot and making it much easier to skim foam off the surface.
