canning (tomatoes)

Hot packing is our method of processing tomatoes (stewed, sauce and juice). Stewing involves skinning the tomatoes before cooking. We start water boiling in the canner. We wash the tomatoes and place then in the laundry tub spread evenly. Next the boiling water is poured over the tomatoes and allowed to set until the skins start splitting. In the meantime clean jars are places in the boiling water bath canner covered with an inch of water. By now the tomatoes are ready to peel. We “pull the plug” to let out the hot water and run cold water over them (easier to handle than hot).
The tomatoes are peeled and cut into quarters into a saucepan to cook. Once the tomatoes and the jars come to a boil, we begin filling the jars. As each jar is filled (leaving ½ inch head space) we wipe the rim, dip the lid with ring attached into the boiling jar water to soften the rubber ring on the lid. Now we apply the lid and tighten firmly. We place the jar back into the boiling water bath and repeat the process, using all the jars and/or tomatoes. Processing time starts when the last jar of tomatoes is in the boiling water. We use quarts so processing takes 45 minutes (35 for pints).
We remove the jars and place on a towel to cool. DO NOT retighten lids. By the time we are done cleaning up the jars are usually sealed. If they aren’t sealed by this time, we check them again in an hour. Any that aren’t sealed by then (very rare) are used within a few days. We then recheck the jar for defects. It’s easy to miss a small chip in the rim, but important to make your best effort. Naturally, we use only recommended canning jars.
