Safe Pressure Canning for Collards and Other Vegetables

Boiling collards on the stovetop before pressure canning does not reduce the required processing time. For safety, low-acid vegetables like collards must reach 240°F for 70 minutes in pint jars to destroy harmful bacteria, including Clostridium botulinum. Stovetop cooking simply doesn't achieve that temperature for long enough.
