How to Can Tomatoes
(using a Steamer or Waterbath)
This is a very easy and simple recipe for canning tomatoes. Because I am using a steam canner, I will not be adding any vegetables. Still, these are a very helpful addition to my pantry.
- Large pot
- large bowl
- clean cloth rag
- butter knife or rubber scraper
- sterilized jars, lids and rings
- steam canner or water bath
- bottle lifters
- hot pads
Here's How to Do It:
Start by rinsing your tomatoes to remove any dirt.
In order to make peeling easier, you will need to blanch the tomatoes. Bring a large pot of water to boil.
Then fill your sink or a large bowl with cold water.
To blanch tomatoes, drop them into the boiling water. Let them sit for about 30 seconds.
Use a strainer to pick them up from the boiling water,
and then dump them into the sink full of cold water.
This will make removing the skins very easy.
Remove the stem end and peel each tomato.
Dice them up to the size you want and drop them into a large, clean bowl (I like to use red so it doesn't stain).
Once your tomatoes are diced, you will be ready to fill up your jars. The only thing you will need to add is vinegar, salt and water (or the extra tomato juice).
Fill tomatoes to the neck of the bottle. If there is juice left in the bowl, pour it over the tomatoes to fill the bottles up completely to the neck (leaving about 1/2 - 1" head-space. If you don't have tomato juice in the bowl, use water to fill up the jars.
For each quart size jar, add 1 tsp. salt and 1 tsp. vinegar.
Now you will need to remove the air bubbles. Use a knife or plastic spatula and run it down the sides of the jar several times.
Use a clean damp cloth and wipe around the tops of each jar, making sure they are clean.
Run your finger around the top to double check that there are no dings or chips in the bottle that would prevent the lid from sealing.
After boiling lids and bands for 1 minute, screw them onto the jars as tightly as possible using one hand. If they are put on too tightly, the bottles will break.
Place jars on rack in steamer/waterbath.
You will need to steam tomatoes (quarts and pints) for 55 minutes. Do not start the timer until steam is consistently coming out.
Put an old towel on the counter next to the steamer.
Once tomatoes are done steaming,
use your bottle lifters to move them from the steamer to the towel to cool.
Using hot pads, tighten the lids as much as possible to help the sealing process.
Once cooled, make sure each bottle has sealed. The lid should be 'sucked in'. If it makes a popping sound, or you manually pushed it down (even if it stayed), the bottle did not seal properly and it needs to be refrigerated and used within 1 week.
Clean off bottles by running them under water and/or wiping them with a damp cloth.
Write the date on the top and put them away!
