Mastering the Art of Canning Tomato Sauce with a Pressure Canner
Canning tomato sauce is a rewarding endeavor that allows you to capture the vibrant flavors of summer produce and enjoy them throughout the year. While traditional water bath canning is suitable for high-acid foods like jams and pickles, preserving tomato sauce requires a pressure canner to ensure proper safety and quality. This essential piece of equipment creates a high-pressure environment that effectively eliminates harmful bacteria, guaranteeing your sauce remains safe and delicious for months to come. Let's delve into the world of pressure canning and discover how to make the most of this technique for your homemade tomato sauce.
Choosing the Right Pressure Canner
The first step in your canning journey is selecting a pressure canner that meets your needs. Two main types of pressure canners dominate the market: dial-gauge canners and weighted-gauge canners.
Dial-Gauge Canners
- Mechanism: These canners use a pressure gauge to monitor internal pressure.
- Advantages: Dial-gauge canners are generally considered more accurate and provide a visual representation of pressure levels.
- Disadvantages: They require regular calibration to ensure accuracy and may have slightly more complex instructions for use.
Weighted-Gauge Canners
- Mechanism: These canners utilize a weighted vent that automatically regulates pressure within the canner.
- Advantages: Weighted-gauge canners are typically simpler to operate and require less maintenance.
- Disadvantages: They may be slightly less precise compared to dial-gauge canners.

Size Considerations:
The size of your pressure canner will depend on your canning volume and frequency. Choose a canner that accommodates the number of jars you plan to process.
Essential Tools for Canning Tomato Sauce
Besides the pressure canner, several additional tools are crucial for successful tomato sauce canning:
- Jars: Choose wide-mouth jars for easy filling and handling. 1-pint jars are a popular size for tomato sauce.
- Jar Rings and Lids: Ensure you have enough jar rings and new lids to seal your jars properly.
- Jar Lifter: This tool safely lifts hot jars from the canner.
- Ladle or Funnel: A ladle or funnel makes filling jars easier and minimizes spills.
- Measuring Cups and Spoons: Accurate measurements are essential for consistency.
- Canning Rack: A canning rack ensures proper water circulation within the canner.
- Pot Holder: Protect your hands when handling hot jars and equipment.
Preparing Tomatoes for Canning
The quality of your tomato sauce depends on the quality of your tomatoes. Here's how to select and prepare the perfect tomatoes for canning:
- Choose Ripe Tomatoes: Look for firm, ripe tomatoes with no blemishes or bruises. Avoid green or overripe tomatoes.
- Wash and Core Tomatoes: Thoroughly wash the tomatoes and remove the core.
- Blanch and Peel Tomatoes: Blanch tomatoes in boiling water for 30-60 seconds to loosen the skin. Immerse them in ice water to stop the cooking process. The skin should easily slip off.
- Chop or Crush Tomatoes: Chop or crush the tomatoes according to your desired texture.
Making Tomato Sauce
- Simmer: Simmer chopped tomatoes in a large pot over medium heat until softened and reduced slightly. This will enhance flavor and thicken the sauce.
- Seasoning: Add desired seasonings like salt, sugar, garlic, or herbs to taste.
- Cook and Reduce: Cook the sauce for 30-45 minutes, stirring occasionally, until it reaches your desired consistency.
Canning Tomato Sauce with a Pressure Canner
- Prepare Jars: Wash and sterilize jars and lids. Place the canning rack in the bottom of the pressure canner.
- Fill Jars: Ladle hot tomato sauce into hot jars, leaving 1/2-inch headspace (the space between the lid and the top of the sauce).
- Wipe Rims: Wipe jar rims with a clean, damp cloth to remove any sauce residue.
- Place Lids and Rings: Place lids on jars and screw on rings, tightening them finger-tight.
- Process Jars: Follow the specific processing time and pressure recommendations based on your altitude and jar size. Here's a general guide:
- 1-Pint Jars: Process at 11 pounds of pressure for 25 minutes.
- 1-Quart Jars: Process at 11 pounds of pressure for 35 minutes.
- Cool Jars: Allow jars to cool completely in the canner without disturbing them.
- Check Seals: Once cooled, check the lids to ensure they have properly sealed. A concave (dented) lid indicates a proper seal.
- Store Jars: Store sealed jars in a cool, dark, and dry place.
Troubleshooting Tips for Pressure Canning Tomato Sauce
- Uneven Heating: If jars don't reach proper temperature, the sauce might not be safely preserved. Ensure jars are fully submerged in water during processing.
- Incomplete Sealing: If lids don't properly seal, the sauce will be susceptible to spoilage. Check lids for any damage or residue before sealing.
- Over-Processing: Over-processing can result in softened tomatoes and a less vibrant sauce. Adhere to recommended processing times.
