Canning Tomatoes
Whether preserving the fruits of labor from your own tomato garden or hoarding those amazing summer farmers’ market tomatoes, canning is a great way to make a seasonal snapshot last all year long. You can also add spices like Izak and Sharwarma West to the jar to make a shaksuka starter that is ready and waiting for you. The process does take some time, so set up a show to binge or call that friend you are long overdue for a catch up with and you will be done before you know it.

Whether preserving the fruits of labor from your own tomato garden or hoarding those amazing summer farmers’ market tomatoes, canning is a great way to make a seasonal snapshot last all year long.

Ingredients
Glass canning jars, clean and dry
New canning lids and rings, clean and dry
Large deep pot (deep enough to submerge the jars)
Large ice bath
Spider or slotted spoon
Lemon juice concentrate
-
Salt
Tomatoes, washed
Spices (optional)
Directions
Bring a large pot of water to rolling boil.
While the water is heating up, remove the cores of the tomatoes and score an “X” into the skin on the bottom of the tomatoes, just deep enough to cut the skin.
Working in small batches, lower the tomatoes into the boiling water (the batch should be small enough that the water is able to continue boiling) for a few seconds, turning as needed.
When the skins have loosened transfer the tomatoes to the ice bath and stir to ensure immediate cooling. Repeat until all tomatoes have been boiled and chilled.
Once cool enough to handle, remove the tomato skins.
Prepare the jars for canning
For each quart jar, add 1 Tbsp of lemon and 1 tsp of salt.
For each pint jar, add 1/2 Tbsp of lemon and ½ tsp of salt.
For whole tomatoes
Place tomatoes in a pot with enough water to cover them. Bring the tomatoes to a boil and pack them into the prepared jars while hot, pouring the boiled water into each jar to cover the tomatoes in liquid. Leave at least ½” of space at the top of the jar.
For diced tomatoes
Cut each tomato in large dice (cutting into 4 wedges and then all in half). Bring the tomatoes to a boil and pack them into the prepared jars while hot, leaving at least ½” of space at the top of the jar.
If you prefer seedless diced tomatoes, cut each tomato in half to make 2 shorts halves and squeeze the seeds out of the halves. Proceed with dicing and boiling as above.
For crushed tomatoes
Cut the tomatoes in half and put them in a pot to boil. As the tomatoes are heating, crush them with a hand blender or potato masher to desired chunkiness. You can also crush them in a food processor cold and then bring them to boil.
When the tomatoes have boiled, pack them into the prepared jars while hot, leaving at least ½” of space at the top of the jar.
If you prefer seedless diced tomatoes, cut each tomato in half to make 2 shorts halves and squeeze the seeds out of the halves. Proceed with crushing and boiling as above.
To season the tomatoes with spices before canning
To season the jars before canning, you can add to the jars and give them a shake once cooled.
If you’re not sure how much to put, you can season the tomatoes to your liking during the boiling step. For example, after boiling the diced tomatoes, pack some jars with the plain tomato and while the remaining tomato dice is hot you could add your blend of choice and season to taste before packing into the jars.
For the Shakshuka starter: add 2 tsp of Izak and 2 tsp of Shawarma West to 1 qt of diced tomatoes.
For a pasta base: add 1 Tbsp of Pizza Posto to 1 pint of diced or crushed tomatoes.
For tomato soup: add 1 tsp of Ararat to 1 pint of diced or crushed tomatoes.
Processing
Make sure the edges of the jars are clean, close the lids, and screw the bands on tightly.
Bring the large pot of water to boil with enough water to cover the jars. Lay a folded tea towel into the bottom of the pot and line the jars into the pot.
Leave to boil for 45 minutes.
Carefully remove the hot jars to a rack or heatproof surface and leave them to cool to room temperature for a few hours.
Test the seals for proper processing. When the rings are removed the lids should not move and be sealed down tight. The jars should be ready to enjoy for up to 1 year.
Recipe Note
Recipe Notes
The tomatoes do not need to be heated prior to canning. The heating helps the tomatoes become more concentrated. The longer you heat them the more concentrated they will become.
Having a mixture of sizes of jars and shapes can be handy. Sometimes you only need a pint and sometimes you need a full quart so feel free to do both sizes. The smaller jar also means a smaller pot.
If you have a canning tool set with the pot, lid, rack, lifter, funnel, etc. this is a perfect time to use them. The directions above are laid out in case you don’t have them.
Variations and Ideas
While the equipment is out in canning mode, this could be a good time to can you own tomato sauce, jams, and soups. Be sure to check processing times and chemical balance for your favorite recipes for canning.
