There are factors that determine what cooking vessel I choose for my cook. What am I cooking? How long is the cook? How long before I cook it? The more insulated your container the less work your Anova has to do. In addition, you can use the ice bath notification feature for longer periods of times if you are using a cooler.
I think everyone here knows by now that I’m a big advocate of the Coleman 24-can and 48-can Stacker coolers but my round Igloo? It can keep a cook on ice for three days before I remote start it.
