Nice Tom! You will love having a vacuum sealer.
And - that "Sous Vide" thing...it's French for "under vacuum". I am sure we will figure out a way to "Muricanize" it... Whatever we call it - it is incredible for what it does for a lot of foods.
How 'bout the "Zip & Dip" method?
It works...sort of....but if you have air in the bag, at least part of the bag will float. And - if the zip-lock bag leaks...you can ruin a meal...
Next step is to wait a couple weeks and then look for the sous vide water heater thing on sale on Amazon
No need to wait Tom! Check out the DSV from Dork Food. They are a sponsor of LTBBQ and have a thread section. If you have a plain knob activated crock pot, or turkey roaster - the DSV will control these - or any other heating element driven appliance that does not have a digital thermostat. And - it is LESS than the other units on the market. I own 3 different Sous Vide devices.
I prefer the DSV for it's versatility, and that I am using a crock pot or turkey roaster for parties- which is are insulated containers with handles that I don't have to make or modify.
