1. Sterilising Canning Jars

The first to do before starting your canning process is to sterilize your canning jar.  There are a few ways to do this:

  • Boil your jars for 10 minutes
  • Put them in the oven at 225 degrees Fahrenheit for 10 minutes
  • Use a dishwasher on the sterilize setting
  • After the jars are sterilized, allow them to cool

2. Prepare The Jars, Lids, And Rings

While the jars are cooling, prepare the lids and rings. The rings do not require any sterilization, but it is a good idea to give them a rinse. For the lids, you have two options:

  • Option 1: Put the lids in a pot of water and bring them to a boil. Boil for 2 minutes, then remove from the heat and let them sit for 2 minutes.
  • Option 2: Put the lids in a pot of water and bring them to a boil. Boil for 10 minutes, then remove from the heat and let them sit for 10 minutes.

Whichever option you choose, make sure you allow the lids to cool before moving on to the next step. Now line up your sterilized jars on the counter. Add 1 teaspoon of sugar and 1 teaspoon of salt to the bottom of each of the jars.

3. Washing Tomatoes

The next step is to wash the tomatoes. There are a few ways to do this:

  • Fill a large stockpot with water and bring to a boil for 2 minutes. Then wash tomatoes twice with hot water and place them in another empty bucket.
  • Fill a large stockpot with hot water. Soak the tomatoes for 15 minutes, to blanch. This process helps in peeling skin easily. After being soaked for a while you will see the skin starting to separate from the flesh.
  • After 15 minutes, skin the tomatoes and cut them into quarters to place them in a large pot.
  • Then as the pot fills up, use a potato masher to mash up the tomatoes. This helps in making canning much easier.

4. Cooking The Tomatoes

After cleaning, peeling, cord, quarter, and smashed, add enough water to the stockpot. Once the pot is full, bring the tomatoes to a boil. Turn the heat down to medium and let the tomatoes simmer for 30 minutes.

5. Canning Tomatoes 

At this point, the tomatoes are ready to be canned. Fill each sterilized jar with tomatoes, leaving 1/2 inch of headspace. If you have any tomato juice leftover from cooking, fill up the jars with that as well. Wipe the rims of the jars with a damp cloth and place the lids on top. Screw on the rings until they are tight, but not too tight. Be careful of the lid, if not closed properly then the tomatoes won’t last longer than 3 to 5 days in the refrigerator.
