Just got one, haven't had a chance to use it yet, but I have a question... The instructions don't discuss using more than one charger, and in fact, state "you only need 1 charger for your iSi ThermoWhip," but I've seen many recipes and bloggers talking about using 2 or 3 chargers. Is this because they're using the 1L GourmetWhip rather than the .5L ThermoWhip? Is the general guideline 1 charger per half liter? As an additional bit of confusion, the instruction bookalsostates "do not use more than 2 chargers for Espumas." So... how many chargers can I safely use in my little half liter ThermoWhip, and is there a reason to go for 2 or 3 rather than 1? Stiffer mousses?

(Inspired by other thread on SVS Professional) I just heard about a deal Costco is doing - a sous vide kit comprising the SousVide Supreme Demi, the SVS vacuum edge sealer, and some accessories for $300. Seems like a good entry level kit or a gift for relatives.

Good tips. I was disappointed with my first water bath eggs... Creamy yolk, but disappointing runny white. Will have to try again with the quick boil. The Lersch blog mentions cooling the egg to room temperature after the bath before boiling, though that may have just been for comparison for the pre-boil/post-boil techniques. In your version, do you cool the egg before the finish step?

I built two (for simultaneous water baths at different temps) based on Tom Ordway's design(itself based on the Seattle Food Geek's design). Here's one with six duck breasts going. Came up with a different mount, though… I didn't have capabilities for bending acrylic, so instead I mounted two of these drum mic clipson the bottom of the heater box. They can rotate slightly, allowing me to securely pin the box to even the curved side of a stock pot. I've also done the 72 hour short ribs with no problem. The heaters pull a lot of current coming up to temperature, but then just a trickle. I've got a huge passive heat sink on the relay, and the controller box stays cool to the touch, even over that time.
