Ziplock bag or vacuum
Sous vide is a French name and literally means 'under vacuum'. When something is vacuumed, there is no air left in it. Do you want to cook sous vide? Then it's your job to get as much air as possible out of the vacuum bag.
'Do I need to buy a vacuuming machine then?' No. This is not a requirement, but it is very handy. Airtight packaging can be done in various ways, although a vacuum packaging machine is the best solution.
Which works better: ziplock or vacuum?
In principle it both works well. However, a vacuuming machine allows more air to be removed than when done with our trick method. Some other advantages of a vacuuming machine:
- Products stay fresh longer
- You can marinate your products within minutes
- Freezing your products keeps them fresh longer
So it is handy to buy a vacuum packaging machine but for sous vide cooking the resealable sous vide bagsare basically enough .
Does this give unhealthy reactions because of the heating of the plastic
Hi Mr. Moolhuizen,
No, the Souvy sous vide bags do not give an unhealthy reaction. The reason for this is that the plastic used is an FDA approved material. However, not all sous vide bags (from other suppliers for example) are made of such high-quality and above all safe material.
