Canning Raw Pack Whole Tomatoes is my favorite way to bring back a little bit of summer during those long winter months.

There is nothing quite like eating a freshly picked, sun ripened tomato. My family is privileged enough to have a small backyard garden and a good section of it is dedicated to a variety of tomato plants – cherry, heirloom, and of course, the thick flesh Roma tomato, which is the perfect tomato to make sauce with.

Every year, there is this mad dash to maximize preservation of fruits and vegetables. It’s no wonder as everything in my garden ripens at once! It’s been a busy couple of weeks, from making Homemade Concord Grape Jelly, to Crock pot Vanilla Pear Butter, and some jars of Chunky Applesauce which will most likely end up as hostess gifts during the holiday season.

So, in an effort to preserve some of my backyard Romas, I spent an afternoon Canning Raw Pack Whole Tomatoes. They will be used for those hearty stews and chunky minestrone soups, appropriate comfort food for the winter. I would like to spend just a few minutes and share this simple process with all of you.

Before I get into the how to, I would just like to bring up a safety issue. As you probably know, when canning tomatoes (or any foods) the level of acidity will dictate the preservation method.

Although tomatoes have always been considered a high acid food, they have recently been flagged as being borderline as far as the pH is concerned (source NCHFP). Remember, a certain level of acidity (pH below 4.6) is required in order to prevent food borne illnesses, botulism for one.

So, like a good little canning soldier, I am following the recommendations. Just in case you are wondering, that means adding a tablespoon of concentrated lemon juice per pint of raw canned tomatoes; two tablespoons if you are using quarts. It is not recommended to use lemon juice (squeezed from a lemon) as lemons can vary in acidity.

Canning Raw Pack Whole Tomatoes by using a water bath method is not difficult, but following a couple of essential steps makes the whole process a lot easier and safer.

STEP 1: The PREPARATION of JARS and TOMATOES

• Canning jars need to be washed and sterilized (place in 225 ° F oven for at least 10 minutes). Leave them in the oven until ready to be filled up;
• Lids also need to be sterilized; just 10 minutes in simmering water is all it takes. Leave them in the water until you need them;
• The rings only need to be properly washed;
• Tomatoes need to be washed. Although any tomatoes can be used, the plum varieties (Roma tomatoes) are the best when it comes to canning. Remember to use tomatoes that are blemish free.

STEP 2: The PEELING of the WHOLE TOMATOES

• Score the tip of the tomato with an “x”  OR just slice off the tip. Personally, I find that slicing the tip off allows for the tomato skin to just slip off once it has been blanched;
• Drop the tomatoes in a pot of boiling water for about 60 seconds;
• Remove tomatoes and place in a bowl to cool down (if you want, you can place them in an ice water bath);
• When cool enough to handle, peel off the skin.

STEP 3: The PACKING and CANNING TOMATOES

• Add one tablespoon of concentrated lemon juice per pint (2 tablespoons if using quarts);
• Fill each hot jar with peeled tomatoes and their juices;
• Leave 1/2 – 3/4 inch head-space from the top;
• Remove air bubbles by running a knife along the side of the jar;
• Wipe the rims clean;
• Place a sterilized lid and screw on the bands until “finger tight”.

STEP 4: The PROCESSING of the CANNED WHOLE TOMATOES

• Place the sealed jars in a lukewarm water bath. Ensure the water is a couple of inches above the jars.
• Bring the water to a rolling boil and start the timing process. Please note that process times can vary based on your altitude. Please refer to this chart for recommendations. I will process my pint jars for about 85 minutes. GOOD TO KNOW: In order to prevent rough mineral deposits on the outside of your jars and on the inside of your water bath pot, pour about 1/2 cup of white vinegar in your water bath.
• Remove jars and allow to cool down before storing.

You’re done! When you hear the seals of the jar lids popping, you’ll know you’ve done a good job!

Origins of the recipe for Canning Raw Pack Whole Tomatoes:

As you can well imagine, Canning Raw Pack Whole Tomatoes, as well as making la conserva di pomodori (i.e. jarred tomato sauce) was a yearly ritual when I was growing up. As most Italians that immigrated to Montreal, my parents had a large vegetable garden which included tomatoes (technically a fruit  😉  )

There was, of course, the obligatory visit to the farms to hand-pick a few more bushels of Roma tomatoes… just in case. You need to know that la cantina was one of the most important rooms in the house and it had to be well-stocked!

And so it was, that as we washed and peeled and jarred tomatoes, stories of childhood memories and lessons of life were shared from one generation to another.

I often look back at those days and think not only were we preserving tomatoes, but creating lifelong memories.

Enjoy the rest of these wonderful summer like days ♥♥♥
