Sterilizing the Mason Jars and Lids

  • There are multiple ways to do this:
    - Dishwasher Method - Some dishwashers have a sanitize function on the dishwasher which works well for preparing the mason jars. The downfall, however, is this can be a time consuming method.
    - Oven Method - Wash the jars with soap, rinse, but do not dry. Place upside down on a baking sheet and put in the oven for 20 minutes at 275 degrees Fahrenheit (130 degrees Celsius). Carefully remove the hot jars for canning.
    - Boiling Method - Wash the jars with soap and rinse. Place jars in a large pot of boiling water (like the water bath canner) and let them sanitize for 20 minutes. Remove jars and let air dry before use.
    For the lids - place in a small sauce pan of hot water until it is time to add them to the jars.

Processing the Tomatoes

  • First wash the tomatoes. Then fill the outer blanching pot (or any large pot) ⅔ full with hot water and bring to a boil. Add the tomatoes and scald for 3 minutes. (The skins will start to crack, indicating they are ready). Place the drainer insert into the sink. Poor the tomatoes from the blanching pot into the drainer insert, and rinse with cold water or ice water. Place the drainer insert with the tomatoes back into the blanching pot to transfer to the Sauce Master Food Strainer.
  • Carefully add the tomatoes to the sauce master and process through the mill. Place a medium bowl below the shoot to catch the tomato sauce or tomato puree, and a small bowl below the open grind end to catch the tomato skins and seeds. See “Important Notes” section below for alternative methods.

Making the Spaghetti Sauce

  • Combine the puréed tomatoes, sugar, and Mrs.Wages Pasta Sauce mix into a large non-reactive pot or saucepan. (There should be about 10 cups of puréed tomatoes - if I am doing multiple batches I will measure out 10 cups for each batch.)
  • Bring to a boil, stirring occasionally. Reduce heat and simmer for 25 minutes, still stirring occasionally.

Water Bath Canning the Pasta Sauce

  • Add hot water to a little over ½ of the water bath canner and bring to a boil.
  • Using a canning funnel and a ladle, pour the hot pasta sauce into the sterilized jars, leaving 1 inch of headspace. Remove air bubbles and wipe the jar rim with a clean damp cloth or papertowel. Using the magnet lid lifter tool, grab the jar lid from the small sauce pan, and carefully place it on the jar. Loosely screw the rings onto the lids to ensure the lids stay in place.
  • Place the jars on the inner wire rack of the water bath canner and lower it into the boiling water. Add the lid to the canner. Process for 40 minutes in boiling water.
  • After the 40 minutes is up, turn off the heat and carefully remove the canner lid. Grab the metal insert by the handles (with oven mitts) and raise the jars up, carefully hooking the handles onto the edge of the water bath canner. Let the jars sit for 5 minutes.
  • Lay out a hand towel or a doubled up flour sack towel on a counter surface. This will act as a barrier between the hot jars and cool counter, preventing the counter and keeping the jars from bursting with the drastic temperature change. Using the jar lifter tool, carefully remove the jars from the wire insert and place them on the towel. Allow jars to sit and cool, undisturbed, for 12-24 hours. Test jars for airtight seals. The lids will not “pop” when pushed down on and will not pop off when pulled up on.

Notes

  • When I first started canning I would submerge the jars under the water, ensuring at least an inch of boiling water would cover the jars. This has been successful. However, I have since learned that is not necessary, and less water is required.
  • Processing time of 40 minutes is appropriate for altitudes less than 1000 feet. For higher elevations, add an additional minute Increase processing time by 1 minute for each 1000 feet altitude above 1000.
  • Tomatoes can have varying pH levels, so adding acid to ensure a safe level of acidity is recommended. For example: 2 tablespoons of fresh lemon juice or bottled lemon juice or ½ teaspoon of citric acid can be added to a quart jar, while 1 tablespoon of lemon juice or ¼ teaspoon of citric acid can be added to each pint jar. A pH level of 4.6 or less will prevent bacteria. However, this isn’t something I have personally ever done and I have never had an issue, and the above is a tested recipe for generations.
  • The sauce master is a great tool that simplifies the process and saves a bunch of time! However, it isn’t required to process the tomatoes. Instructione for processing without a sauce master: Scald the tomatoes for 3 minutes, remove the peels and cut out the core. Run through a blender, immersion blender, or food processor or blender until smooth and drain off excess liquid.
