Pressure Canning: A Step-By-Step Guide

The lid of a pressure canner has a vent or a petcock to allow steam to escape

Leda Meredith

Fasten the pressure canner lid on (how varies depending on which brand you’ve got). Leave the vent pipe or the petcock open. Turn the heat on high if it isn’t already (see previous step #3). When steam begins to escape from the vent or petcock vigorously, start timing. Follow the manufacturer’s instructions for how long to allow the steam to exhaust. If unspecified, let it go for 10 minutes.
