Heating one liter of water in the Kona Cooker
Photographs of a thermometer poking out of a pot lid with water being heated in a Kona Cooker.
Water pasteurizes at 150F/65C to make it safe from germs.
The text below the images tell the time and temperature along with consequences for each temperature stage.
If a pot with a tight fitting lid is used the contents should heat faster than this demonstration.
