A bad jar can look, smell, and taste normal and still be lethal.
Follow tested charts exactly (NCHFP, USDA, Ball): times, pressures, venting, altitude, nothing improvised.
Germany's Einwecken tradition is water-bath; it is not enough for low-acid food.
Test a dial gauge every year; a weighted gauge never needs it.
Boil home-canned low-acid food 10 minutes before eating; bin any suspect jar untasted.
An Instant Pot or pressure cooker is not a canner unless tested and labelled for it.
