Melting/reusing aerated chocolate?

Recommended Posts

I made aerated chocolate using the recipe from Greweling's "Chocolates & Confections." However, the air bubbles are not very big and I'm not a huge fan of the finished result. I would much prefer to reuse it in a different form. Any idea if it would be possible to melt and reuse the couverture? Or is it doomed since now it has a bunch of O2/NO in it? I worked so hard to get the bubbles in and now I want them out! 😣

Should be fine.

I'm considering that recipe.  Could you say any more about your experience making it?

I'm not that person but I've done both his and Heston Blumenthal's versions many times. Heston's version is easier because the chocolate isn't tempered so you can keep the temperature much higher going into the whipper. I've had issues with clogging from solidified chocolate doing Greweling's method a couple times. Makes for a fun whipper cleanup. Heston also adds a small amount of a neutral oil to his version,. He claims it helps with the bubbles and it gives a final texture closer to the commercial aerated chocolate I've had. Regardless of which method is used, you get much larger bubbles by shooting the chocolate into whatever it's being molded in, tossing it in a vacuum sealer, pulling a vacuum until the chocolate expands and leaving it in there to set before releasing the vacuum. I don't own a chamber sealer and no longer have access to the one I used to use so I haven't done the aerated chocolate in a long time. It was really just a novelty thing that was fun to do for a bit anyway, I don't often find myself missing it.

Clogging the iSi is what I am afraid of.  I did the experiment of placing a mold of chocolate in my chamber vacuum sealer and I indeed got bubbles.  In that case, unintended bubbles.

Heston still uses the whipper. He sprays it from the whipper into the mold and then immediately goes into the vacuum sealer. It makes for almost ridiculously big bubbles if you pull it far enough. If you pull it too far, it collapses.

Thanks Kerry! Will proceed to reuse 😁

I can echo Tri2Cook's experience of having the nozzle clogged. Clean up was a drag! I found that the chocolate cooled down too quickly, even when heating up the whipper to the 90 F. I guess that's why Heston's recipe/method has its appeal, but I didn't want to create a vacuum seal!

Turn off the sealing function for doing this.

The suggestion I saw was to turn on the chamber vac - when it reaches the neg pressure you want - flip it off. It will stay sealed with the same negative pressure. After enough time for the chocolate to set - turn it on again to release the vacuum.

I thought @chanjying meant the bag sealing function.

But if you let it go through the cycle it will still release the vacuum - this way you can keep it under vacuum until it solidifies.

My Polyscience has a cycle for holding vacuum.

I find Heston's version easier to work with even if you don't bother with the vacuum chamber. The resulting bubbles are as good as the bubbles I get from Greweling's version even without the vacuum. The vacuum can be used with Greweling's version as well to get better bubbles and eliminates the added oil... just have to work quick and hope chocolate doesn't harden in the nozzle when charging the whipper. That's the only difficulty I had with Greweling's version, the low starting temp of the chocolate because he calls for it to be in temper.

      Serious help please 😬
      In production of airbrushing many moulds at a time:
      Paint and scrape the mould immediately for each mould every time After scraping the mould you cant get everything off so you need to clean each mould on paper As a result paint from the edges of the mould chips off  Please see picture attached and if anyone has any suggestions it would be greatly appreciated.  
      Any tricks on scraping and cleaning moulds after airbrush when in production.
       
      Thank you

      Hey Guys,
       
      I have just managed to acquire two secondhand 2016 Selmi One's at a good price, but they did not come with operator manuals. Since the very first thing I want to do is give them as thorough a clean as I can, I feel having access to a manual is vital, and yet I don;t seem able to find one online. As such, I have reached out to the UK agent, but thought I would also ask here if anyone has a digital copy they could ping me?
       
      I'm really excited to have purchased these two Selmi's following some outside investment in my chocolate racing helmet business. Also within the next couple of days, both Mario Andretti and Fernando Alonso will be tasting my creations, which if you know anything about motorsport, is kind of a big deal
       
      Cheers guys!
       
      Matthew

      I am a new start up in chocolate making. I tried to freeze a container with my bonbons and all the caps just cracked after using my simple vacuum machine. Please help! Which containers should I use and how do you vacuum pack these containers. Anyone with a picture of the container would help.
      thank you

      WANTED: Chocovision tempering machine. 
       
      Looking for a gently used tempering machine. Anyone have one they like to sell?
       
      thanks!

      So I seem to be doing the thing where the more I find out and learn about chocolate the more I realize I don't know.  
      I'm wondering how little I can get away with spending in the very beginning. My husband is back in school and I'm wondering if chocolate experimenting is even feasible right now or if its something I should wait on. 
      I figure I can practice tempering and molding at a low cost, but from there does it get steep?
