I'm curious about this.
Most sous vide cookers are built like a "stick" with an immersion heater and something that circulates the water.
Would it work directly in soup, or would the food particles foul the mechanism?
Even with pot style sous vide cookers,the circulation mechanism could be compromised.
The Insta pot style pressure cookers usually have a sous vide setting, but I don't think you can set the temperature precisely.
If a sous vide cooker won't work directly, it could be used in a cooler full of water.
Cut holes in the lid of the cooler, one for the sous vide stick, one for a stock pot.
Much simpler and cleaner than my industrial level diy double boiler, much cheaper than a commercial one.
