- Never can pasta sauce that’s been left at room temperature for more than 2 hours.
Altitude Adjustments
If you live at a high altitude, you’ll need to adjust the processing time for your pasta sauce. This is because water boils at a lower temperature at higher elevations, which can affect the safety of the canning process.
To adjust for altitude, use the following guidelines:
- 1,000-2,000 feet: Add 5 minutes to the processing time
- 2,000-3,000 feet: Add 10 minutes to the processing time
- 3,000-4,000 feet: Add 15 minutes to the processing time
- 4,000-5,000 feet: Add 20 minutes to the processing time
Testing Your Pasta Sauce for Safety
After canning your pasta sauce, it’s essential to test it for safety. This involves checking the jars for signs of spoilage and ensuring that the sauce has been heated to a safe temperature.
To test your pasta sauce for safety:
- Check the jars for signs of spoilage, such as swelling, leakage, or mold.
- Open a jar and check the sauce for any signs of spoilage, such as off odors or slimy texture.
- Use a candy thermometer to check the temperature of the sauce. It should be at least 212°F (100°C).
What to Do If Your Pasta Sauce Isn’t Safe
If you notice any signs of spoilage or if the sauce hasn’t been heated to a safe temperature, it’s essential to take action. This may involve re-canning the sauce or discarding it altogether.
To re-can your pasta sauce:
- Re-heat the sauce to a minimum temperature of 212°F (100°C).
- Re-pack the sauce into clean, hot jars, leaving about 1/2 inch of headspace.
- Re-process the jars in a boiling water bath for 35-40 minutes, adjusting for altitude as necessary.
