Buying advice
1) Cut a slot in the lid sized to your circulator (a jigsaw or box cutter; measure first). 2) Fill with water to your target depth. 3) Run the circulator — the insulation cuts heat loss and evaporation dramatically. 4) Use it for big batches, long cooks, and even no-power cooking (pre-heated water holds hours).
FAQ
Is a cooler better than a tub?
For big batches and long cooks, yes — insulation means fewer heating cycles and less evaporation.
Do I have to cut the lid?
No — you can just set the circulator in with the lid ajar, but the slot makes it efficient.
What cooler is safe?
Any food-grade plastic cooler with a good seal — most are.
