Preserving the flavors of summer in a jar is a rewarding experience, and nothing beats the taste of homemade tomato juice. Whether you’re an experienced canner or a beginner, this guide will walk you through how to make tomato juice for canning. Let’s dive into the process and create a pantry staple that’s perfect for soups, sauces, or even a refreshing drink!
Why Make Your Own Tomato Juice?
Homemade tomato juice isn’t just about saving money—it’s about controlling the quality of what you consume. Store-bought options often contain preservatives or added sugars, while your homemade version will be fresh, flavorful, and free of unnecessary additives.
What You’ll Need
Before you start, gather the following equipment and ingredients:
Equipment:
– Large stockpot
– Food mill, sieve, or blender
– Water bath canner or pressure canner
– Canning jars with lids and bands
– Wide-mouth funnel
– Ladle
– Jar lifter
– Clean towels
Ingredients:
– Fresh tomatoes (approximately 23 pounds for 7 quarts of juice)
– Bottled lemon juice or citric acid (to ensure safe acidity levels)
– Salt (optional, for flavor)
Step-by-Step Instructions
1. Prepare Your Tomatoes
Start by selecting ripe, high-quality tomatoes. Wash them thoroughly under running water to remove any dirt or debris.
Blanching:
- Bring a large pot of water to a boil.
- Dip the tomatoes into the boiling water for 30–60 seconds until the skins split.
- Immediately transfer them to a bowl of ice water to cool.
- Peel off the skins and remove the cores.
2. Cook the Tomatoes
Cut the peeled tomatoes into quarters and place them in a large stockpot. Heat them over medium heat while crushing them with a spoon or potato masher. This helps release their juices.
Continue adding more tomato quarters to the pot as you crush them, ensuring that the mixture stays at a steady boil. Once all the tomatoes are added, simmer for about 5 minutes.
3. Strain the Juice
Using a food mill, sieve, or blender (followed by straining), process the cooked tomatoes to remove seeds and skins. This step ensures a smooth consistency.
Return the strained juice to the pot and bring it back to a gentle boil.
4. Acidify for Safety
Tomatoes are borderline between high-acid and low-acid foods, so acidification is crucial to prevent harmful bacteria like botulism.
– Add 2 tablespoons of bottled lemon juice or ½ teaspoon of citric acid per quart jar.
– For pint jars, use 1 tablespoon of bottled lemon juice or ¼ teaspoon of citric acid.
You can also add 1 teaspoon of salt per quart (optional) for flavor.
5. Fill Your Jars
Using a wide-mouth funnel, ladle the hot tomato juice into sterilized jars. Leave ½ inch headspace at the top to allow for expansion during processing.
Wipe the rims of the jars with a damp cloth to ensure a proper seal. Place lids on top and secure with bands until fingertip-tight.
6. Process Your Jars
Choose your preferred method for canning:
Water Bath Canning:
- Place jars in a water bath canner with enough boiling water to cover them by at least 1 inch.
- Process pint jars for 35 minutes and quart jars for 40 minutes at altitudes below 1,000 feet.
- Adjust processing times based on your altitude if necessary.
Pressure Canning:
- Process pint or quart jars at 6 pounds pressure for 20 minutes or 11 pounds pressure for 15 minutes, depending on your altitude.
7. Cool and Store
After processing, carefully remove jars using a jar lifter and place them on a towel-lined surface to cool undisturbed for 12–24 hours.
Check seals by pressing down on the center of each lid—if it doesn’t pop back, it’s sealed properly! Store your canned tomato juice in a cool, dark place for up to one year.
Tips for Success
– Always use bottled lemon juice or citric acid instead of fresh lemon juice to ensure consistent acidity levels.
– Avoid overfilling jars; leaving proper headspace is key to preventing leaks during processing.
– Label your jars with the date so you can track freshness.
Making your own tomato juice for canning is not only satisfying but also ensures you have a versatile ingredient ready whenever you need it. So roll up your sleeves and get started—you’ll thank yourself when winter rolls around!
