First off boil your jars to sterilize them and turn them upside down on a clean towel. Next get your tomatoes ready to go by washing them.

I turned them upside down and cut an X in the bottom of them.

Then I put them in boiling water for about 1 minute.

I scooped them out and peeled off the skin. It comes off real easy if you do this.

Next I cut the tops off and cut them in half so they would fit in the jars.

I put them in the jars leaving about 1 inch at the top. Squish them down so the air pockets dissapear.

Boil the rubber seal lids for about 5 minutes to soften up the rubber.

Screw the lids and rings on hand tight and put them in some boiling water. You have to use a fairly large pot here. A pressure cooker is what a lot of people use for this. There has to be at least 2 inches of water over the top of the jars. They cannot touch the bottom of the pan. Elevate them with a rack if you have it. I didn't have one so I took an old aluminum pie tin and cut holes in the bottom of it and turned it upside down before putting the jars in the boiling water. This way they were elevated from the direct heat.

Let them boil for at least 20 minutes. This sterilizes the tomatoes. Don't leave them too long or you will cook your tomatoes.
Remove them from the boiling water. There are some special canning tongs you can get but I just used regular ones and grabbed the jars with a towel right away and put them on the towel to cool off.

Within a couple of hours as they cool down you will hear a loud click as the lids seal and form a vacuum. They are sealed at this point and ready to be stored away for winter tomato dishes. You can use the handle part of a spoon and tap the tops. The sealed ones will make a click sound and the unsealed ones will make a clunk sound.
NOTE - 2 of my jars didn't seal. I didn't leave these 2 long enough in the boiling water. To fix this you can use the hot pack method instead of the water bath method. I poured the contents of the jars into a sauce pan and got them boiling hot. Then I poured them back into the jars and put the lids and rings back on hand tight. They sealed in about 30 minutes with the click sound. In fact the hot pack method can be used as an easier way to can. You just have to make sure the jars are boiled to sterilize them, the lids are boiled to soften up the rubber rings, and the tomatoes are real hot but not cooked to make the heat inside the jar draws the lid down and make the seal.
Of course salt to taste but I have high bp so I use less or no salt. I hope this helps anyone that wants to can tomatoes.
