Essential Supplies for Canning Tomatoes
Canning tomatoes needs special tools and supplies for safety and quality. The right equipment makes the process easier and more fun. Here are the essential canning supplies you need, like jars, a water bath canner, and other tools for a successful canning journey.
Canning Jars, Lids, and Bands
Choosing the right canning jars is key. Glass jars made for food preservation are safe and durable. You also need lids and bands to seal the jars well. Make sure to pick quality lids; avoid one-piece lids for safety reasons.
Standard jar sizes are pint and quart. They can hold about 1 quart of tomatoes from 2 1/2 to 3 1/2 pounds of fresh tomatoes. Check your jars for cracks or chips before filling. Brands like Ball offer reliable jars and accessories.
Using a canning jar lifter like the Ball Secure-Grip can make lifting jars easier and safer.
Water Bath Canner and Equipment
The water bath canner is crucial for processing tomatoes. It should be at least 4 to 5 inches deeper than your jars. A 12-inch depth is best for quart jars. This ensures the jars are fully submerged for even heating.
If you don’t have a water bath canner, a large stockpot can work. It should be at least 12 quarts and tall enough for your jars. A 5-quart colander is handy for preparing tomatoes. Keep your home canning tools organized for a smoother process.
Preparing Your Tomatoes for Canning
Preparing tomatoes for canning is key for safety and flavor. Start with the right preparation and tools. This part covers cleaning canning jars and how to peel tomatoes and dicing tomatoes for canning.
Cleaning and Sterilizing Jars
First, clean your canning jars well. Use hot, soapy water to wash jars, lids, and rims. Make sure to remove all residues from previous uses.
After washing, sterilize jars to avoid contamination. Simmer jars in boiling water for about 10 minutes. This step also warms the jars for filling with hot tomatoes.
Peeling and Dicing Tomatoes
Now, prepare your tomatoes. The best way to peel tomatoes is by blanching them. Boil them for 30 seconds to 1 minute to loosen the skin.
Then, quickly put the tomatoes in an ice water bath. This stops the cooking and makes peeling easier.
Next, dice tomatoes for canning. Cut peeled tomatoes into quarters and remove any bad spots. You’ll need about 12 pounds of tomatoes for 4 quarts of canned product.
Once your tomatoes are ready, start canning. For detailed canning instructions, visit this resource.
How to Can Tomatoes: The Basics
Canning tomatoes is a rewarding task. It lets you keep your garden tomatoes fresh all year. You can use a boiling water canner or a pressure canner for tomatoes. Knowing how to use these tools is key to preserving your tomatoes at home.
Boiling Water Canner Overview
A boiling water canner is great for high-acid foods like tomatoes. It works by dipping jars in boiling water. This creates a seal and keeps bacteria out.
For canning tomatoes, quart jars need about 45 minutes at low altitudes. Pint jars take about 40 minutes. Adding 2 tablespoons of lemon juice per quart helps keep the tomatoes fresh and safe.
Pressure Canner Usage
Even though tomatoes are acidic, sometimes you need a pressure canner. This is true when tomatoes are mixed with other foods that aren’t as acidic. A pressure canner uses higher heat to kill off bad bacteria.
At sea level, quart jars need about 85 minutes in a pressure canner. Always check the jar seals after they cool down. This is important for keeping your canned tomatoes good.
| Canning Method | Processing Time (Quarts) | Processing Time (Pints) | Acidity Maintenance |
|---|---|---|---|
| Boiling Water Canner | 45 minutes | 40 minutes | Add 2 tbsp of lemon juice per quart |
| Pressure Canner | 85 minutes | N/A | Adjust per recipe requirements |
Learning these basic canning methods helps you make delicious, safe tomatoes. You can enjoy them all year in your cooking.
Step-by-Step Canning Process
When you start canning, every detail matters, especially when filling jars. Each step is key to keeping your tomatoes safe and tasty. Here’s how to fill jars, add acidity, and get the right headspace.
Filling the Jars with Tomatoes
Begin by blanching your tomatoes to make their skins easy to remove. Boil them for 30 to 60 seconds, then cool them in ice water. This works best for tomatoes like Roma.
When you fill the jars, pack the tomatoes tightly. This helps keep the juice in and air out.
Adding Acid: Why Lemon Juice is Important
Adding acidity is crucial for canning tomatoes safely. Each quart jar needs 2 tablespoons of lemon juice or ½ teaspoon of citric acid. This step stops bacteria from growing and makes the tomatoes taste better.
You can also add salt for extra flavor. Use 1 teaspoon per quart, but it’s not required.
Ensuring Proper Headspace
It’s important to have a ½ inch headspace in your jars. This helps the lid seal properly and prevents spills during processing. Don’t add extra water when packing raw tomatoes.
Instead, let the tomatoes’ natural juice fill the jar. This keeps the acidity right and helps preserve the tomatoes well, whether you use pressure canning or water bath canning.
Processing Your Jars
Processing jars is key to canning tomatoes safely and well. It involves following specific timing and temperature rules. This ensures your food stays safe and tastes great. Whether you use a boiling-water bath or a pressure canner, focus on this step for good seals and long storage.
Timing and Temperature Guidelines
For different jar sizes, exact processing times are needed:
| Process Type | Jar Size | Processing Time | Pressure (PSI) |
|---|---|---|---|
| Boiling-Water Bath | Pints & Quarts | 90 minutes | N/A |
| Dial-Gauge Pressure Canning | Pints & Quarts | 25 minutes at 11 PSI | 11 PSI |
| Weight-Gauge Pressure Canning | Pints & Quarts | 25 minutes at 15 PSI | 15 PSI |
For effective processing, keeping the right temperature is crucial. In boiling-water bath canning, keep the water simmering. For pressure canning, use the correct PSI for your method.
Cooling and Sealing the Jars
After processing, cool the tomatoes carefully. Place jars on a clean towel or rack, allowing air to circulate. A distinct snap or pinging sound means a vacuum seal has formed.
To check the seal, gently tap the lid after cooling. If it doesn’t move, it’s sealed. Also, look for a slight concave shape on the lid. This confirms a secure seal. Proper sealing is essential for safe storage of your canned tomatoes for up to two years or more.
Storage Tips for Canned Tomatoes
Storing your canned tomatoes right is key to keeping their taste and quality. Knowing the best storage conditions can make your canned tomatoes last longer. This way, you can enjoy them for months.
Optimal Storage Conditions
Here are some tips for storing canned tomatoes:
- Temperature: Store them in a cool, dark spot. The best temperature is between 50°F and 70°F.
- Light Exposure: Don’t let them sit in direct sunlight. Sunlight can damage the cans and affect the taste.
- Humidity Levels: Keep the humidity low. This prevents rust and mold on the cans.
Following these tips will help keep your canned tomatoes fresh and safe to use all year.
How Long Do Canned Tomatoes Last?
The shelf life of canned tomatoes depends on how you store them and the canning method. Generally, they can last:
- Up to 1 year for the best taste when stored properly.
- 2 to 3 years for safety, but the quality might drop after a year.
Always check for signs of spoilage before using them. Look for bulging lids, rust, or an unusual smell. These signs mean the tomatoes might not be safe to eat.

Common Canning Mistakes to Avoid
Canning is a great way to keep your harvest fresh. But, there are common mistakes that can spoil your food or make it unsafe. Knowing about these mistakes, like sealing problems and how to fill jars right, can make your canning better.
