How to Can Whole Tomatoes with a Water Bath: 

Step One:

Pick your tomatoes and wash them.

Step Two:

First, fill your water bath canner half way with water. Place the lid on and bring to a boil.

Step Three:

Next, put your lids and rings together. Place them in your small stock pot and cover them with water. Then put the lid on the pot and bring it to a boil. 

Step Four:

Fill a large stock pot with hot water and bring to a boil. This boiling water will be used for blanching the tomatoes. 

Step Five:

Next, you will need to prep your jars. Fill CLEAN jars with HOT water. This will acclimate them for the hot tomatoes. They need to be up to temperature so that they will not bust and also so that they will seal properly. 

Step Six:

When you are making water bath canned tomatoes, it is likely that you will need to top off some of the jars of tomatoes with hot water. So, you will need to fill a tea kettle or electric kettle with water, and bring it to a boil. 

Step Seven:

Now it’s time to blanch your tomatoes! First, fill your sink with ice water. Next, place your washed tomatoes into the boiling water in the large stock pot. Allow them to sit in the boiling water for 1-2 minutes.

Once you see the skins start to split, they are ready to transfer into the ice water to shock them. You will use a metal strainer with a handle to transfer the tomatoes from the boiling water into the ice water.

Step Eight:

Once the tomatoes are submerged in the ice water, you will need to move quickly to remove the skins. Place the skinned tomatoes in one bowl, and the scraps in another. If the tomatoes are large, you can cut them in half. 

Step Nine:

Empty the jars of the hot water. Pack the tomatoes into the jars and add boiling water from the tea kettle to top off if needed. Clean the rims of the jars thoroughly with a damp tea towel or dish cloth.

Step Ten:

Next, use your tongs to remove the lids and rings from the boiling water and screw them onto the jars tightly. 

Step Eleven:

Once the lids are secured, you will need to use your canning tongs to gently place the jars into the boiling water. Allow them to boil in the water bath canner for 40 minutes.

Step Twelve:

Lastly, you will remove the jars from the canner and place them on a towel to allow them to cool completely. I usually leave my jars untouched over night. As the jars cool, the lids should seal. You will hear them make popping noises. Once the lids have sealed, you can remove the rings and reuse them. 

It’s a really good idea to rinse the jars with warm water to clean any residue from the tomatoes. This will prevent mold from growing on the outside of the jars. And finally, dry the jars, label them, and store in a cool, dark place.
