Water bath canning is a simple and effective method of preserving food by creating a vacuum seal in a jar. This method involves submerging jars filled with food and liquid in a large pot of boiling water, which helps to kill off any bacteria and create a vacuum seal as the jars cool. Water bath canning is ideal for high-acid foods like fruits, pickles, and tomatoes, as these foods are naturally acidic and can withstand the heat of the water bath without losing their texture or flavor.
Benefits of Canning Tomatoes in a Water Bath
Canning tomatoes in a water bath offers several benefits, including:
- Long-term preservation: Canned tomatoes can be stored for up to 12 months, making them a great way to enjoy fresh tomatoes throughout the year.
- Easy to use: Canned tomatoes are convenient to use in a variety of recipes, from soups and sauces to salsas and salads.
- Cost-effective: Canning tomatoes at home can be more cost-effective than buying canned tomatoes at the store.
- Customization: By canning your own tomatoes, you can control the amount of salt, sugar, and other ingredients that go into your canned tomatoes.
Preparing Tomatoes for Canning
Before you can start canning tomatoes, you need to prepare them properly. Here are some steps to follow:
Choosing the Right Tomatoes
Not all tomatoes are suitable for canning. Look for tomatoes that are high in acid, such as Roma or Plum tomatoes, as these will be easier to can and will result in a better flavor. Avoid using low-acid tomatoes, such as Cherry or Beefsteak tomatoes, as these may not be safe for canning.
Washing and Blanching Tomatoes
Wash the tomatoes thoroughly in cold water to remove any dirt or debris. Then, blanch the tomatoes in boiling water for 10-15 seconds to loosen the skin. Remove the tomatoes from the water and immediately submerge them in an ice bath to stop the cooking process.
Peeling and Chopping Tomatoes
Once the tomatoes have cooled, peel off the skin and chop them into small pieces. You can also crush or puree the tomatoes if you prefer a smoother texture.
Canning Tomatoes in a Water Bath
Now that your tomatoes are prepared, it’s time to start canning. Here’s a step-by-step guide to canning tomatoes in a water bath:

What is water bath canning and how does it work?
Water bath canning is a method of preserving food by heating it in a boiling water bath to kill off any bacteria and create a vacuum seal. This method is ideal for high-acid foods like tomatoes, fruits, and pickled vegetables. The process involves packing the food into clean, sterilized jars, adding a brine solution or syrup, and then heating the jars in a large pot of boiling water.
The boiling water bath heats the food and the jars, killing off any bacteria and creating steam. As the jars cool, the steam condenses, creating a vacuum seal that prevents new bacteria from entering the jar. This seal is what preserves the food and allows it to be stored for long periods of time. Water bath canning is a simple and effective way to preserve food, and it’s a great way to enjoy your homegrown tomatoes year-round.
