Choose a safe path

Before you begin

Use a tested recipe from a reliable source, identify whether it calls for boiling-water, atmospheric steam, pressure canning, or another specifically approved process, and apply the recipe’s altitude instructions. Do not substitute ingredients, jar sizes, processing times, pressures, or methods unless the tested source allows it.
