Essential Safety Tips for Pressure Canning

Pressure canning allows you to preserve low‑acid foods like vegetables, meats and soups safely, but the higher temperatures and pressures call for caution.

**Safety Tips:**
– **Use a tested recipe:** Follow USDA‑approved or trusted canning guides; tinkering with recipes can alter acidity.
– **Check your gauge:** Have dial gauges tested yearly to ensure accuracy; weighted‑gauge canners don’t require calibration.
– **Allow proper venting:** Let steam escape for 10 minutes before closing the vent to remove air and build pressure correctly.
– **Adjust for altitude:** Increase pressure or processing time based on your elevation.
– **Never force cool:** Allow the canner to depressurize naturally before opening; rapid cooling can cause jars to break.

Respecting these guidelines ensures your pressure‑canned foods are safe to eat and shelf‑stable.
