I was very surprised to see that the Sousvide Supreme was today available in Europe (Kookpunt.nl – Netherlands) at € 599 (incl. shipping?).
No star Chef, no Heston Blumenthal for the introductory in Europe of the so called  “water oven”?
So strange that the Sousvidesupreme (USD 449 in the US) is now almost as expensive as a Grant SV100 immersion circulator and 30% more expensive than a swid! Please keep in mind that, contrary to what was said in several articles on internet,  the Sousvidesupreme is not an immersion circulator but a non stirred water bath (PID controlled).

Today Polyscience made the demonstration that a non stired water bath cannot be as efficient as an immersion circulator. It is funny to see that Polyscience directly mentions Sousvidesupreme in the TAG of the article.

Polyscience video indicates clearely that a non stired water bath has a longer response time to reach the desired core temperature. Therefore, it is obvious that Douglas Baldwin cooking tables sould be used with care. Douglas Baldwin indicates in the Pratical Guide to Sous Vide “With all these digital controllers, I highly recommend setting the temperature offset (measured near the temperature at which you wish to cook) using a high quality digital thermometer. Indeed, at the default settings the thermistors used in the above controllers can easily be off 2–4°F (1–2°C)”.

Freshmealsolutions mentions clearely in the user manual of the SousVideMagic : “If you don’t have a proper food core temperature sensor probe, always cook at desired core temperature settings for the duration as specified by reliable recipes with an additional safety factor of at least 25% longer…”
In addition the manual indicates “The default settings are designed to overshoot 1 or 2 degree higher for safety reasons. You can reduce the overshoot by making your own PID adjustments. See the document “PID Tuning”.”
