Canning yellow tomatoes is the same as canning red tomatoes. When water bath canning, acidify tomatoes by adding bottled lemon juice or citric acid to the canning jars and process for 85-100 minutes in a boiling water canner.
What is the Best Way to Can Yellow Tomatoes?
The best way to can yellow tomatoes is by processing them in a water-bath canner. To process them in a boiling water canner, they must first be acidified by adding bottled lemon juice or citric acid.
The National Center for Home Food Preservation recommends pressure canning low-acid foods or pickling them before water bath canning. Since yellow tomatoes are less acidic than red tomato varieties, it is important to raise their acidity before canning if not using a pressure canner.
How to Prepare Yellow Tomatoes for Canning
- Pick ripe tomatoes without blemishes, as bruised and overripe tomatoes have lower acid levels.
- Rinse tomatoes under running water to remove dirt and debris.
- Blanch the tomatoes in boiling water for 30-60 seconds until the skin begins to split.
- Remove them from the hot water with a slotted spoon and submerge them in ice water to prevent cooking.
- After cooling the tomatoes, peel them using clean hands or a sharp knife.
- Leave tomatoes whole or cut them into halves or quarters, if desired.
- Pack tomatoes into prepared canning jars and fill the jars with hot water or tomato juice, leaving 1/2-inch headspace.
- Wipe the rims of the jars and top the jars with new canning lids.
- Add screw bands and tighten until fingertip tight.
How to Prepare Canning Jars for Canning Yellow Tomatoes
- Inspect canning jars for cracks, defects, or imperfections.
- Wash the canning jars in hot, soapy water.
- Rinse the jars thoroughly to remove traces of soap or detergent.
- Sterilize the jars by submerging them in clean boiling water with the rims facing up for 10 minutes.
- Remove the jars from the hot water using canning tongs and place them on a clean towel to dry.
Is Canning Liquid Required for Canning Yellow Tomatoes?
Canning liquid is not required when raw-packing yellow tomatoes, but it is recommended for most canning applications.
Water and tomato juice may be used as canning liquids for whole or halved yellow tomatoes. Maintain 1/2-inch headspace when water bath canning or 1-inch headspace when pressure canning with canning liquid.
Are Yellow Tomatoes Good for Canning?
Yellow tomatoes are good for canning. This type of tomato can be canned using the same method as canning red tomatoes and green tomato varieties.
Yellow tomatoes have a sweeter taste because they have less acidity, which requires using a bit more citric acid or bottled lemon juice when canning them. Canned yellow tomatoes are great for making tomato salsa, puree, ketchup, and spaghetti sauce.
Why Do People Believe You Shouldn’t Can Yellow Tomatoes?
There’s a prevailing notion that yellow tomatoes are a low-acid food and unsafe for water bath canning.
However, they have an average acidity and contain more natural sugar than other types of tomatoes.
Experts recommend adding ½ tablespoon of citric acid or 2 tablespoons of bottled lemon juice per quart jar to make canned yellow tomatoes safe for water bath canning. For pints, 1 teaspoon of lemon juice or ¼ tablespoon of citric acid should be added.
What is the Difference Between Canning Tomatoes and Canning Tomato Juice?
While one is a product of the other, there are three key differences between canning tomatoes and tomato juice:
When preparing tomatoes for canning, you wash, peel and core them before packing them in jars.
Conversely, preparation for the juice includes cleaning tomatoes, boiling them in a saucepan while crushing continuously, then removing skin and seeds using a food mill or sieve.
2. Processing Time
Processing sealed tomato jars takes 85 minutes in a water bath canner and 40 minutes when pressure canning.
On the other hand, canning tomato juice requires 35 to 40 minutes for the boiling water bath canning method and 20 minutes if using a pressure canner.
3. Quantity of Ingredients
Canning tomatoes requires fewer ingredients than making tomato juice. You’ll need 23 pounds of tomatoes for juice and 21 pounds for canning tomatoes per 7-quart canning load.
What are the Benefits of Canning Yellow Tomatoes?
Canning yellow tomatoes has numerous benefits, including:
- Convenience: Whether preparing your favorite soup or tomato sauce, canned yellow tomatoes are easily accessible.
- Cost-effective: Home canning reduces food waste, and commercially prepared products cost more.
- Packed with nutrients: Canned yellow tomatoes provide niacin, lycopene, folates, and vitamins A, C & K.
- Promotes self-sufficiency: Having canned tomatoes is great for emergencies.
- Saves time: With jars of tomatoes in your pantry, fewer visits to the grocery store are needed.
- Tastes better: Home-canned tomatoes have better flavor than commercially prepared options due to fewer additives.
