In this article, we will explore proven techniques to improve your preserving and preparing canning tomatoes whole, half, and juice. Whether you're a seasoned canner or just starting out, these tips and tricks will help you to achieve the best results.
Understanding the Basics of Canning Tomatoes
Before we dive into the techniques, it’s essential to understand the basics of canning tomatoes. Canning involves packing tomatoes into airtight containers, known as jars, and then heating them to kill off any bacteria or other microorganisms that may be present. This process, known as sterilization, helps to preserve the tomatoes and prevent spoilage. There are several key factors to consider when canning tomatoes, including the acidity level, the type of tomatoes used, and the canning method.
Acidity Level and Tomato Variety
Tomatoes are naturally acidic, with a pH level of around 4.2-4.5. However, some tomato varieties are more acidic than others, which can affect the canning process. For example, acidic tomatoes like Roma or Plum tomatoes are ideal for canning, as they have a higher acidity level than other varieties. On the other hand, sweeter tomatoes like Cherry or Beefsteak tomatoes may require additional acidity, such as lemon juice or vinegar, to ensure safe canning.
Canning Methods
There are two main canning methods: water bath canning and pressure canning. Water bath canning is suitable for high-acid foods like tomatoes, and involves submerging the jars in boiling water for a specified period. Pressure canning, on the other hand, is used for low-acid foods and involves heating the jars to a higher temperature using a pressure canner.
| Tomato Variety | Acidity Level | Canning Method |
|---|---|---|
| Roma | High | Water Bath |
| Cherry | Low | Pressure Can |
| Plum | High | Water Bath |
Preparing Tomatoes for Canning
Before canning, it’s essential to prepare your tomatoes properly. This involves washing, sorting, and chopping the tomatoes, as well as removing any stems or leaves. For whole tomatoes, you’ll need to blanch them in boiling water for 10-15 seconds to loosen the skin, and then peel and pack them into jars. For half tomatoes, you can simply chop them in half and pack them into jars. For tomato juice, you’ll need to cook the tomatoes down to extract the juice, and then strain and pack it into jars.
Blanching and Peeling Tomatoes
Blanching and peeling tomatoes can be a bit time-consuming, but it’s an essential step in preparing them for canning. To blanch tomatoes, simply drop them into boiling water for 10-15 seconds, and then immediately plunge them into an ice bath to stop the cooking process. The skin should then peel off easily, leaving you with a smooth, skinless tomato.
Cooking Down Tomatoes for Juice
Cooking down tomatoes to extract the juice is a simple process that involves heating the tomatoes over low heat until they break down and release their juice. You can then strain the juice through a cheesecloth or fine-mesh sieve to remove any solids and achieve a smooth, clear juice.

Canning Tomatoes Whole, Half, and Juice
Canning tomatoes whole, half, and juice requires attention to detail and a reliable canning recipe. For whole tomatoes, you’ll need to pack them into jars, leaving a small headspace, and then add a brine solution and seal the jars. For half tomatoes, you can simply pack them into jars and add a brine solution. For tomato juice, you’ll need to pack the juice into jars, leaving a small headspace, and then seal the jars.
Packing and Sealing Jars
Packing and sealing jars is a critical step in canning tomatoes. You’ll need to use a reliable canning funnel to pack the tomatoes or juice into the jars, and then add a brine solution and seal the jars using a clean and sanitized lid and ring.
| Tomato Type | Packing Method | Brine Solution |
|---|---|---|
| Whole | Pack into jars | Water, salt, and lemon juice |
| Half | Pack into jars | Water, salt, and lemon juice |
| Juice | Pack into jars | None |
What is the best way to store canned tomatoes?

+Yes, you can can tomatoes without a pressure canner, but it’s essential to use a reliable canning recipe and follow safe canning practices to avoid spoilage and foodborne illness. Water bath canning is suitable for high-acid foods like tomatoes, but it’s essential to use a acidity tester to ensure the tomatoes are acidic enough.
How do I know if my canned tomatoes are spoiled?
+Check the jars regularly for signs of spoilage or damage, such as swelling, leaking, or mold. If you notice any of these signs, it’s best to err on the side of caution and discard the jar.
