    Use Your “Potto” For Pasta

    By thomas | March 4, 2008

    denki pottoDo you have a potto? No, not the tailless ape. I mean a denki potto (電気ポット). A denki potto is a hot water machine. People use it to make coffee and tea. We keep one plugged in at our house to make baby formula, cocoa and tea. It’s very convenient.

    Another use for the potto is when you are making pasta, soup or any other food that requires a large quantity of boiling water. Instead of pouring water from your sink and waiting 10 minutes to get it to boil, pour water from your potto! You’ll have a pan full of boiling water in a very short time. Our denki potto keeps the water at 90 degrees Celsius. That’s not far from boiling!

    If you don’t own a denki potto, you can buy one pretty cheap. A low-end one costs about 4000 yen.

    Do you have any denki potto tricks? Let me know in the comments.

      Use Your Denki Potto For Fast Boiling Water |…

      When you make pasta or soup, do you start by filling a pan with water from the sink? That’s the slow way! Here’s a trick for getting water to a boil very quickly….

      Does a denki pot consume more or less energy than old fashioned boiling? I’m just curious as to which method is more efficient overall.

      I use it for thawing frozen veggies in a flash. No cooking, just soak in hot water for about 30 seconds and drain for wonderful peas and corn. It makes really quick oatmeal and al dente instant ramen, too!

      I too would like to know which takes more energy overall. That would make an interesting study.

      @joseph and NPC: I have no idea as I have never measured the energy, but I would imagine the the potto would use much more. I usually have mine plugged in all day so that there is always hot water ready when I need it (to make baby formula, tea, or whatever). So I imagine I use a lot of energy just having the potto sit there all day. Boiling water with a fire probably takes much less. But it takes way more time :)

      @Pouncy: Great tip! That deserves a post of its own! Thank you!

      This reminds me of that video on Japan Probe with the woman making spaghetti and meat loaf in a rice cooker (link). It’s amazing how much time or money a little creativity can save.

      But, what if you also want a cup of hot coffee with your soup and you’ve just emptied your hot water machine to make the soup?
      Your microwave oven でんしレンジ probably has a “milk” preset button. Put your cup of water in there, hit the button and it reaches 60+ degrees celsius real fast.

      I think this may violate this blog’s prime directive: saving money. Probably not all that eco-friendly either.

      Re: violating of this blog’s “prime directive,” it says right up there at the top that this is for *time-* and money-saving tips. Denki potto is definitely a time-saver, no doubt about it. As for money, at least according to Japanese version of, average potto usage costs around 912 yen/month, or just under 11,000 yen per year. (

      True enough; time is money.

      Definitely one of the things that I miss now that I’m back in the states… I went looking for one at the nearby Korean grocery store, but they were definitely going for more than 4,000 yen on this side of the Pacific >_

      Wo kann ich einen Denki Potto kaufen?

      Hallo Freunde des Denki Potto,

      der Denki Potto scheint eine Kombination aus einem Wasserkocher mit Warmhaltefunktion und einer Thermoskanne zu sein, so daß das Wasser nicht nur durch Nachheizen auf Temperatur gehalten wird, sondern auch durch thermische Isolation der Energieverlust reduziert wird. Außerdem sollen sie über eine Zeitschaltung verfügen, so daß man steuern kann zu welchen Zeiten heißes Wasser bereitgehalten werden soll. Also ein ideales Gerät für Tee-viel-Trinker. Nun ja – ob man so etwas wirklich braucht, ob es nicht auch ein ganz normaler Wasserkocher tut, sei dahingestellt, trotzdem möchte ich gern wissen, wo in Deutschland oder Europa solche geräte verkauft werden.
      Grüße Ulrich Flasche

      When I first purchased my potto, I checked out energy useage. 5yen/day. Now, I will assume that means it costs 5yen/day to maintain the water at 98C for 24 hours.
      Thus, the only additional cost would be the heating of the water, which will be more efficient since
      a) excess water is not being heated and wasted
      b) the pan is not being heated
      c) surrounding air is not being heated

      I am not an Engineer, nor have I done any calculations to verify my thinking…..

      The above plus the convenience of having a potto, is a hands down winner for me to have it plugged in 24/7.

      One note: Electricity is twice as expensive as natural gas, and I did not take that into my consideration.
