Preserve Your Tomato Harvest
By Nancy Noon
It seems like we are coming to the end of garden season; the gardens and farmers markets are overflowing with fresh tomatoes, onions and peppers. So much bounty at once, sometimes it is hard to deal with it all. In this case, any little bit you can do every day helps to preserve your harvest or your farmers market purchase for those winter months when you would do anything for a good tasting tomato!!
Here are a couple of recipes from tested sources for canning salsa:

Crushed Tomatoes

Crushed Tomatoes
Wash tomatoes and dip in boiling water for 30-60 seconds or until skins split. Then dip in cold water, slip off skins and remove cores. Trim off any bruised or discolored portions and quarter.Â
Heat about 1 pound of the quarters quickly in a large pot, crushing them with a spoon or potato masher as they are added to the pot. This will draw off some juice. Continue heating the tomatoes, stirring to prevent burning. Once the tomatoes are boiling, gradually add remaining quartered tomatoes, stirring constantly. These remaining tomatoes do not need to be crushed. They will soften with heating and stirring. Continue until all tomatoes are added. Then boil gently 5 minutes. Add bottled lemon juice (1 tbsp per pint, 2 tbsp per quart) or citric acid (1/4 tsp per pint, ½ tsp per quart). Add ½ tsp salt to each pint jar; 1 tsp to earch quart if desired. Fill hot jars with hot tomatoes, leaving ½ inch headspace. Remove air bubbles. Adjust lids and process.Â
Boiling water bath or steam canner: Pints, 35 minutes, Quarts 45 minutesÂ
Pressure Canner at 10 pounds pressure: Pints or Quarts 15 minutes.Â

You can also make your favorite sauce recipe, and freeze it. Sauce freezes beautifully.Â
If you want to can sauce, you will need to use a tested recipe.
Here are some favorites:

Of course, if you have no time to deal with tomatoes now, you can freeze them until you have time. Just wash, core, and store in gallon bags in your freezer. When they are thawed, the skins slip right off. These are best used for crushed tomatoes, or sauce, as the texture becomes a bit too soft for salsas.
