Arrrgh... well maybe this attempt will work, but making silk so far has not been easy.
I have a pretty good and inexpensive Sous Vide. I've confirmed temperatures with a separate thermometer that I trust.
But first what I tried:
* I took a big mason jar with a flip top glass & rubber lid and put 4oz of cocoa butter in there. I use a weight to hold the mason jar down in the water. I've tried too different types of water baths described below.
* My target temp was 92.5F (the Sous Vide has 0.5F temp steps).
* My first attempt used a medium size cooler with I would say a few gallons of water in it. The water temp was stable at 92.5, but after 24 hours I still had solid cocoa butter. Raising 0.5 degrees to 93.0F and after 24 hours I still had solid cocoa butter. Raised another 0.5 to 93.5F and at some point the Sous Vide gave up - I may have dialed in the time wrong - the water temp dropped down to the 70s and of course I had solid cocoa butter...
* Second attempt I took a much smaller stock pot. Put the large mason jar in there with a weight on top (the very top of the jar is no submerged). After 24 hours I still had solid cocoa so I went up 0.5F to 93.0F. I'll know the results tomorrow.
But what am I doing wrong? Is the container too big? Has anyone tried just using a zip-lock with cocoa butter in it? Getting the seal right is of course pretty critical, but I would dry it off at the end and squeeze the silk out into another plastic container to let it set.
Thanks in advance for any help!
