We found some good looking beef shanks at the store. We had a beef-beet stock tucked away in the freezer. It seemed to be a good time to bring the two together. We thawed out the stock and put it in a vacuum bag with the shanks. We are cooking the shanks for 24 hours in the CVap at 57°C. When we are done we should have an intense beet flavored shank and shank flavored borscht. The next steps will be influenced by the results.
