When to Use a Water-Bath Canner

Water Bath CannerWater-bath canning is ideal for preserving high-acid foods, such as jams, jellies, applesauce, tomato sauce, and whole tomatoes. These foods are naturally less prone to spoilage due to their high acidity levels, making the hot-water bath sufficient for safe preservation.

Pro Tip: Always ensure your jars are properly sterilized before starting. Using a water-bath canner remains a beginner-friendly and reliable way to preserve many pantry staples.

When to Use a Pressure Canner

Pressure CannerFor preserving low-acid foods, such as green beans, corn, squash, or meats, a pressure canner is essential. Unlike the water-bath method, pressure canning allows for higher temperatures, which are necessary for safely processing foods with low acidity. These higher temperatures eliminate bacteria like Clostridium botulinum, ensuring your canned goods are safe and long-lasting.

Pressure Cookers Are Not Pressure Canners

It's a common misconception that pressure cookers can double as pressure canners. However, pressure cookers do not maintain the precise pressure levels required for safe canning and are often too small to accommodate the necessary jar sizes. For detailed information on safe canning practices, refer to the University of Wisconsin's Food Safety guidelines.

First Steps for Using a Pressure Canner

  • Wash all equipment: Clean your canner, jars, and lids with hot, soapy water.
  • Check for imperfections: Run your fingertips around jar tops and lids to ensure a smooth surface for a proper seal.
  • Inspect rubber rings: Ensure they’re flexible and free from cracks.
  • Clear the vent pipe: Make sure there are no blockages in the canner’s vent pipe.
  • Lubricate seals: If using a metal-to-metal seal, apply petroleum jelly for optimal performance.
  • Prepare the water: Fill your canner with at least 1 1/2 inches of water. Never let it boil dry.
  • Use a canner rack: Always place jars on the rack to prevent breakage during processing.
