MC Aerated Chocolate, Vacuum Set Foams

Hey all,

I came across a few recipes for vacuum set foams in Modernist Cuisine and would love to give them a shot. I do have a chamber vac but am a bit reluctant to run a vacuum and unplug the machine in the middle of a cycle. Can anyone speak of the reliability of this technique? Should I be concerned about damaging my machine?

Nothing to be concerned about, all you are doing is stopping the evacuation mid-process, the vacuum seal remains. When you restart your machine, the seal will break. To verify your specific machine, contact your manufacturer.

It won't damage the machine, I have done it to many kinds. But cheaper ones dont really hold a vacuum very well, they leak over time. So if your has the capacity, like Multivacs do, you can set a hold pressure. And the machine will sleep, if the pressure goes beyond a given range the machine will pull additional vacuum.

Otherwise, just try it. You won't hurt the machine.

To echo the others, I've stopped the machine mid vacuum plenty of times both on purpose and accidentally without any problems. You could also consider separate containers with one-way valves like the foodsaver accessories if your chamber has an accessory port.

Much appreciated Grant! I have been reluctant to try this for fear of ruining my machine. I've been trying to achieve the same thing by not having the bag extend over the seal bar and pulling multiple cycles for compression uses.
