Ingredients:

- 3 kg fresh, ripe tomatoes

- Salt and pepper to taste

- Lemon juice

- Herbs if desired (basil or parsley work very well)


Equipment:

- Pressure canner

- Canning jars with lids and bands

- Canning funnel

- Jar lifter

- Lid lifter or magnet

- Bubble remover tool or non-metallic utensil

- Clean towels or racks for cooling


Step 1: Prepare the Tomatoes

Start by washing the tomatoes thoroughly and removing any stems or blemishes. There's no need to worry about peeling off the skin for this recipe, but make sure you cut off all the dodgy bits.


Step 2: Blend the Tomatoes

Using an immersion blender or a countertop blender, carefully blend the tomatoes until you have achieved the desired consistency. I prefer a chunkier sauce to be used with a seafood pasta, where I can still bite into a small piece of tomato.


Step 3: Season the Sauce

Put the blended tomato mixture in the pot and put on medium heat, season with salt and pepper to taste. Adjust the seasoning according to your preferences and add your choice of chopped herbs.


Step 4: Prepare the Canning Jars

While the tomato sauce is simmering, prepare the canning jars and lids. Wash them in hot, soapy water and rinse well. Keep the jars warm until ready to use.


Step 5: Fill and Seal the Jars

Using a canning funnel, carefully ladle the hot tomato sauce into the prepared jars, leaving about 1/2 inch of headspace at the top. Remove any air bubbles by running a bubble remover tool or a non-metallic utensil along the sides of the jar. Wipe the rims of the jars with a clean, damp cloth to ensure a clean seal. Place the lids on the jars, then screw the bands on fingertip tight.


Step 6: Pressure Canning Process

Follow the instructions provided with your pressure canner for the proper pressure and processing time. Place the filled jars in the canner, ensuring they are upright and not touching each other. Secure the lid of the pressure canner and heat it according to the manufacturer's guidelines.


Step 7: Processing Time

Process the jars at the recommended pressure for the specified duration. Generally, for tomato sauce, a pressure canning process at 11 pounds of pressure for 25-30 minutes is suitable. However, it's essential to consult your pressure canner's instructions for precise guidelines based on your altitude and canner model. I have processed mine at 12 psi for 35 minutes.


Step 8: Cooling and Storage

After the processing time is complete, turn off the heat and allow the pressure canner to depressurize naturally. Once depressurized, carefully remove the jars using a jar lifter and place them on a towel-lined surface or cooling rack. Please do not put the jars too close together or cover them with the towel, as it creates a potential environment for "Flat sour Bacteria" (more about that in a different post). Let the jars cool undisturbed for 12 to 24 hours. During this time, you may hear the satisfying "pop" sound as the lids seal. After cooling, check the seals by pressing down on the center of the lids. If the lids do not move or make a popping sound, they are properly sealed. Label the jars with the date and store them in a cool, dark place.


Conclusion:

With this easy recipe , you can efficiently and deliciously preserve your tomato harvest! Pressure canning provides a safe and reliable method for long-term storage, ensuring you have a convenient supply of homemade tomato sauce ready to elevate your family's meals throughout the year. Embrace the art of pressure canning and enjoy the satisfaction of having a versatile and flavourful sauce at your fingertips whenever you need it.

Happy canning!
