🔥 Heat Processing

Pressure Canning

Use a pressure canner to reach 240°F+ and safely preserve low-acid foods like vegetables, meats, and soups.

📋 Step-by-step
1

Follow a tested low-acid canning recipe exactly — never guess processing times.

2

Inspect your pressure canner gasket and vent tube before each use.

3

Fill jars per recipe instructions and place on a rack in the canner with recommended water level.

4

Vent steam for 10 minutes before closing the vent and building pressure.

5

Process at the pressure and time specified for your altitude.

6

Allow pressure to drop naturally; do not force-cool the canner.

💡 Helpful tips
  • Have your dial-gauge canner tested annually for accuracy.
  • Use only canning jars — never reuse commercial glass food jars.
  • If a jar does not seal, refrigerate and use within a few days.
⚠️ Safety note
Improper pressure canning of low-acid foods can cause botulism, which is odorless and potentially fatal. Always use tested recipes.
