Three months ago I tried a soft boiled egg at 63°C during 1 hour. I have admitted that it was not the perfect egg for me and promissed to make another try. This time I cooked an egg 50 minutes at a constant 64.5°C temparature.

And here is the result!

 The egg at 64.5°C has nothing to do compared to the 63°C one (see the last picture down this post). The appearance of the 64.5°C is better, the white egg is more compact and doesn’t fall down like the 63°C one.

The yolk is also very different compared to the 63°C one.

See bellow the picture I made 3 months ago of the 63°C soft boiled egg with the Sousvidemagic and above the 64.5°C egg with the swid of Addélice. This is crazy to see how a difference of only 1.5°C can change so much the texture of an egg.
As I told it before I didn’t really like the 63°C egg but the 64.5°C was fantastic!! Absolutly incredible…I strongly recommend anybody trying it!
I read on internet that such egg was impossible to do without the precision and stability of an immersion circulator. I know understand why. If the temperature variation is equal or higher to 1°C then this can change the final texture of the white egg and yolk. The cool thing is also to be sure to reproduce the same result each time you set your immersion circulator at 64.5°C! I am definitely getting found of this cooking equipment.

Sous vide cooking with a temperature PID controller (SousVideMagic of Fresh Meals Solutions)

by on Jun.12, 2009, under Equipments & Accessories, General Topics

I am now very happy and relieved to jump to the next step of my experimentation consisting in trying all kind of sous vide cookers and accessories. Cooking sous vide with a gas stove, a halogen stove or a basic water bath (bain-marie) was such a pain in the neck! The main advantage of this was the cost of the equipments, close to zero (except for the vacuum machine) but it was really hell to maintain a constant temperature.

Let’s try a PID controller!
But first what is a PID (Proportion, Intregral, Derivative) temperature controller?

The PID temperature controller is the most sophisticated controller available providing exceptional performance at a surprisingly low price. But what is it, really?

Here are 4 articles that should help you understand it!

The first link is the most accessible information I could find about a PID controller. Let’s call it “PID controller explained for dummies”. This fantastic video was made by robot geeks and explains speed PID controller. You just have to replace into your mind speed by temperature! This video is a bit long to download but if you would have to watch one piece of information about the PID controller in your life time I would strongly suggest you to watch this video!

This second link is giving a little more information about temperature PID controller (still understandable for an average intelligent brain).

Here are 2 links that I would recommend for people who are really interested in tuning PID controllers. In other words, don’t even dare clicking on these links  if your are not a scientist!

Sous vide cooking with a rice cooker paired with a temperature PID controller.

A rice cooker or other heating appliance will cycle on and off, causing fairly wide temperature fluctuations. To avoid this some people pair a rice cooker with a PID controller. The PID controller has a thermo-sensor that is inserted into the rice cooker water. You set the PID device to a certain temperature, and the PID will control the amount of electricity that activates the heater, thus keeping the water temperature at a constant.

Although other heating appliances can also work, the simple rice cooker seems best suited to work with the PID device for sous vide applications. You must buy a rice cooker that has a basic mechanical on and off switch. Don’t purchase an expensive sophisticated rice cooker, it will probably not work with the temperature PID controller.

What are the temperature PID controllers available on the market for sous vide cooking purposes?

SousVideMagic 1500B form Fresh Meal Solutions

sous-vide-cooking-org-temperature-pid-controller-sousvidemagic-fresh-meal-solutions

I purchased the SousVideMagic 1500B as it seems to be the most popular one. Feedback of people who purchased it is excellent. The cost for this temperature PID controller is USD 169 plus approx. USD 25 shipping costs to Europe (USD 99 if you don’t have the patience to wait, therefore you’ll get it within 3 days with Fedex).
For non North American users an input power cord and an adaptor to the socket of local standard will have to be purchased separately.

To sum up, the global cost for my SousVideMagic temperature PID controller is:

  • SousVideMagic 1500B: USD 169 + USD 25 = USD 194 incl. sending
  • Custom duties: EUR 35
  • Basic rice cooker: EUR 45
  • Input power cord and socket adaptor: approx EUR 16.

Grant total (1 EUR = 1.4 USD): approx. EUR 234 (USD 327)

I sould receive my SousVideMagic tomorrow. I’ll give you my first comments as soon as possible!
