If you have an abundant harvest of tomatoes, canning is an excellent way to preserve their freshness and flavor for year-round enjoyment. This step-by-step guide will show you how to easily and effectively can your tomatoes, ensuring they stay delicious and safe to use in your favorite recipes.
Step 1: Preparing the Tomatoes
The first step in the canning process is to prepare your tomatoes. After harvesting, place them in the refrigerator overnight. Chilling the tomatoes makes peeling easier and more efficient.
Step 2: Blanching the Tomatoes
To remove the skin easily, heat a pot of water until it is very hot but not boiling. Drop the cold tomatoes into the steaming water and let them sit for about one to three minutes. Once you notice the skins splitting, carefully remove them from the water and let them cool.
Step 3: Peeling and Cutting the Tomatoes
Once the tomatoes have cooled enough to handle, peel off the skins. If there are any blemishes, cut them off, along with the top core. After peeling, chop the tomatoes into small pieces and place them in a stockpot.
Step 4: Heating the Tomatoes
Slowly heat the chopped tomatoes on medium-low heat. This gradual heating process helps prevent scorching. Stir frequently to ensure even cooking. As the tomatoes warm up, preheat your canning jars in the oven at 250°F to sterilize them.
Step 5: Preparing the Lids and Jars
While the tomatoes are heating, place the canning lids in warm water to soften the seals. This step ensures a tight fit when sealing the jars.
Step 6: Filling the Jars
Once the tomatoes reach a simmering point, carefully ladle them into the preheated jars. Fill each jar up to just below the rim, leaving adequate headspace. Add one teaspoon of salt to each jar to enhance flavor and aid in preservation. Wipe the rims with a damp paper towel to ensure a proper seal.
Step 7: Sealing and Processing the Jars
Place the lids on top of each jar and tighten the bands securely. Once sealed, turn the jars upside down and let them sit for about five minutes. This helps create a vacuum seal. After five minutes, turn the jars upright and allow them to cool. Within 30 minutes, you will hear a "ping" sound, indicating that the jars have sealed properly.
Step 8: Storing the Canned Tomatoes
After cooling overnight, check the seals by pressing down on the center of each lid. If the lid does not move, the jar is sealed correctly. Store your canned tomatoes in a cool, dark place such as a pantry for long-term storage.
