I just purchased a new Demeyere Atlantis 3.5 qt conical sauteuse with lid. It is a beautiful piece and very worthy of all the positive comments.
I tested it on my portable induction (Vollrath Cadet) with a watt miser that measures the watts consumed. I found it to be very responsive. On high setting (20) it drew a full 1850 watts which was nearly 200 watts higher than any other pan (cast iron, Tramontina clad stock pot or Cuisinart clad stock pot). This supports Demeyere's claims of their induction efficiency. It resulted in boiling water approx 15% faster than any other pan or stock pot. Impressive! It makes me want to try an Atlantis stockpot, even with it's high price.
The issue I have with the conical sautuse is the lid. It doesnt fit like I would expect. It is pretty loose and when on it is very easy to slide it laterally and right off the edge of the pan without lifting it.
This seems strange so I visited SLT to look at the Industry5 conical sauteuse. I found the lid to fit much better than the Atlantis. It sat solidly and could not be slid sideways without lifting it. I did not take my Atlantis sauteuse into the store, but noticed the Industry5 lid profile to be slightly different, the rolled portion seems to extend into the pan further making it more secure. Both pans have a similar rolled lip.
The lids on my Cuisinart stock pot and Tramontina fit much better than the Atlantis sauteuse. Has anyone else experienced or noticed this? I won't be using the lid much, but somehow expected more given the high price and Demeyere's specific description of a "Perfect Fit" and a hermetic seal and ability to hold in steam. I can post some pictures later.
