This technique allows us to explore a particular feature that the Vacuum Packing Machines have. Through a vacuum, accompanied by an inverted cold bath, we can obtain aerial creations.
In order to prepare chocolate volcanic stones, you can use a small container in the vacuum chamber, or you can use Vac-Norm containers with a lid and a vacuum valve that afterwards, will be introduced into a blast chiller.
For this kind of creations you need raw materials with high fat content such as sheep milk, fats like chocolate, pralines, butter, etc.
This is an example which shows that the possibilities of the Vacuum Packing machines go beyond mere food preservation.
Bon appétit !
