Choose a variety of tomatoes to can together, or if you prefer a thicker juice use Roma tomatoes. Big Boy, Celebrity and Early Girl will have more juice so good for those juicing drinks. This fruit, is loaded with antioxidants and is full of flavor.
If you dont have a tomato press, use a simple mill to remove skins and seeds.
Wash and clean your tomatoes, be sure to remove any bad spots and discard any tomatoes that are overly ripe or show signs of decay or rot.The juice heating on the stove top. Heat to a low rolling boil for 10 minutes before canning
Dice up tomatoes into smaller 1/2″ to 3/4″ chunks – enough to fill a 6 or 8 quart stock pot
Place stock pot on medium low heat and let the tomatoes start to cook down slowly – making sure to stir every 5 minutes or so to prevent burning on the bottom of the pan.
As the tomatoes cook down – we like to add a few more fresh-cut tomatoes to keep the stock pot full.
Using a ladle to fill up the jars.
Continue to cook down tomatoes until they become soft and fall apart at the touch.
At this point – we run our tomatoes through our food mill to remove the skins and seeds and squeeze out the juice. We use the tomato press because of the quantity – but for small batches – the food mill will work great.
Once all the tomatoes have been run through – return the liquid into a stock pot and begin to heat through on medium to medium high heat. You want to get the tomato juice to a slow rolling boil.
Wipe the top of your jars and place on the lids.
Let boil for 10 minutes and you are ready to can.
Sterilize your pint or quart jars by running through your dishwasher – and then heat the jars and warm the lids in a separate stock pot.
Add your juice to heated jars, along with a teaspoon of lemon juice. The lemon juice will not change the flavor – it is only included to help increase the acid level. Although almost all tomatoes will already be high enough in acidity for canning – it is a simple extra step to insure safety. As an optional ingredient – you can also add a half teaspoon of salt per quart jar for taste.
Water bath for 10 minutes
Wipe the rim, and seal with a warm ring and lid. Process in a hot water bath for 10 minutes.
Remove jars and place on a towel and let cool for 24 hours before storing, Check to make sure all jars are sealed by pushing on the lid – if the lid is down and won’t move it is sealed appropriately. If not – immediately place in your refrigerator and use within 2 weeks.
As a general rule of thumb – one 8 qt. stock pot full of tomato juice will yield enough to can about 7 quart jars
Quick Tip: instead of discarding the skins and pulp put them in the dehydrator and make tomato powder!
