We've had an Anova circulator for about a year and a half and love it. After an incident involving loud beeping at 4AM due to too much water evaporation, it was time to put together a dedicated setup. It is actually pretty inexpensive – about $30 all together.
- 12 Quart Rubbermaid Commercial Space Saving Food Storage Container - can use a bigger or smaller one depending on what you tend to cook – I think this is a good size for most.
- Rubbermaid Commercial Plastic Food Storage Container Lid with a corner cut out – don't buy one of those bespoke lids they make unless you like burning twenties.
- IKEA VARIERA expanding pot lid organizer – can turn this whichever way best holds what you're cooking. In this picture I have salmon fillets slotted in with the rack on what I guess you'd call its front, which keeps everything submerged and separated for optimal circulation.
For this meal, I took salmon straight out of the freezer in their individually packed bags and tossed them in 120°F water directly for 45 minutes (or more precisely, I put them in before filling with water and then started the timer when the water came to temp). Then I patted them dry, seasoned them, and seared them on the stove. A+, will do again.
