Page 15 - Sous Vide Que

But you don’t need a vacuum sealer. You can use a plain old zipper bag and squeeze out the air by sliding it into a pot of water so that the water pressure pushes the air out, called “Archimedes principle of displacement.” Then zip it. At temperatures above 160°F, the seams of some zipper bags fail and water can get in. Use heavy duty vacuum sealing bags for higher temperatures. You can buy special sous vide bags and zipper bags on Amazon. Click here to watch a video on how to remove air from a zipper bag without a machine.
If you use heat sealable bags, fold the opening back into a wide cuff before inserting the food. Then unfold the cuff to seal the bag.
