Tomato Canning

It’s September and that means one thing – yes, the start of school and the return to an insane schedule of shuttling between activities but more importantly, it’s tomato-canning time!

For the past few years we have spent an entire Saturday from sun-up to well past sundown, making the most delicious tomato sauce that will last for the entire year.

From veal cutlets to pasta and grilled cheese to pizza, this basic sauce is the perfect pairing for just about anything and really, what tastes better than a bit of summertime in the bleak days of winter?

Finding tomatoes is easy peasy.  Most farmers markets and Italian grocers stock bushels of tomatoes in addition to peppers, beans and cucumbers.  If you’re lucky a few Nonas will share their secrets to jarring while standing in the (inevitably) long line-up.  This year we decided to double our usual supply and went for 4 bushels.

I like to pre-wash the tomatoes.  This gets rid of the sand but also acts as a quality control step.  Any badly bruised or rotting tomatoes are discarded.  The boys like to get in on this step and it does help speed up the process.  Once they are washed, cut them length-wise in half.

Then boil them on the stove for about 20 minutes.   Some people choose to skip this step and others insist that it’s necessary in order to get the most juice from the fruit.  It’s up to you, but apparently we’re suckers for extra work.

When the tomatoes are finished boiling, scoop them out with a sieve and push them through an electric tomato-squeezing machine like this one.  In the past, we have done this by using a large food processor.  The downside of the food processor method is that your sauce will end up with seeds and it takes time. It’s tedious.  Very tedious.  The electric machine allows you to push the halved tomatoes through at a much faster pace discarding the skin, seeds and cores while pureeing the fleshy pulp into a juice.  The machine is an investment so if your unsure this is for you, I would suggest renting one first.

Four bushels of tomatoes yields a lot of tomato juice.  I use every large container I can find in the house – including a toy storage bin!  I’m just going to say it – be sure to wash all containers thoroughly.  No one wants surprises in their sauce.

While one person (or if you’re smart, you’ll have a team) will continue with the tomatoes, someone else can get started on the garlic.  Many people choose to jar just the tomato juice.  We take it a step further (I told you that we love extra work) and make a nice garlic sauce.  It adds hours to the process, but when it’s 5:30 pm on a Tuesday in February and the three boys are melting down with hunger and fatigue and I have a raging fever with a sore throat that feels like knives every time I swallow, I can rest assured that I have a dinner!  Boil pasta, add the sauce and bingo-bango, everyone is happy and I can resume dying on the couch.

Back to the garlic.

We used 24 heads of garlic.  They were small in size, but we do like our garlic around here.  I spent about an hour peeling and chopping before my brother stopped over and told me his garlic trick.  Slice the top and bottom off the head of the garlic and pop it in the microwave for about 40 seconds.  The cloves slide right out of the “paper”!  Needless to say, the process went much quicker after his visit.

All burners will be a go now.  Get some pots on the stove (the bigger, the better) and sauté some of that garlic in olive oil along with chili peppers and/or onions (if taste buds agree).  Pour in the freshly pureed tomato juice, add some salt and cook on high heat.  Stir constantly.  When the sauce starts boiling, turn the stove down to medium.  Allow the sauce to cook until it turns a nice orangey-red.  See the difference (note: the picture doesn’t show it as well as I had hoped)?  The red one is not done yet . . . it will take time, and lots of taste tests to ensure it’s perfect.  This is where a fresh baguette comes in handy.

Not quite ready. It's still too red.

See the nice orangey-red colour of the sauce and the rim around the pot? It’s ready!

While the sauce is bubbling away, sterilize your jars in the dishwasher.  The lids need to be done on the stove in a pot of boiling water (See?  More pots and more burners being used).

Once they are sterilized, pour 2 tbsp of lemon juice into each jar.  Some people add salt.  Some use citric acid.  Those Nonas at the grocery store will all tell you something different but when in doubt check with Google.

When the sauce is ready, ladle it into the jars, filling to an inch within the top.  Add the snap-lid and ring.

Place the sealed bottles into a pot of boiling water (we’re are using the burner that is attached to our BBQ) for about 15 minutes.  The pot we have can only take seven jars at a time.  Perhaps we should look into renting a second burner and larger pot for next year.

Remove the jars from the pot and after the jars have cooled check the snap-lid.  If the centre of the lid is clicking it’s not sealed.

Store your stockpile of sauce like a mad-couponer who just scored a deal on toilet paper.

We made 68 bottles of sauce this year.  I guess we do have traditions after all.

  1. WOW, very proper work!!! My recipe is a little easier- but with some seeds… I cook the tomatoes with garlic, onion, parsley and other herbs, strain it, put it in nice bottles and cover it with 1 centimetre of olive oil. This method is also good for soup and sauces in the wintertime. With kind regards from Austria!!!

    • Phew! It is a lot of work but so far we’re happy with the results. I enjoy hearing how other people can their tomatoes. Everyone has their own unique way of doing it. I do think, for next year, I want to do something more basic too (like you have described) for soups – so that I have a good base from which to work. Thank you for sharing!

  2. BA, can’t believe I didn’t comment when this first came up… I am in awe! Love that the whole family helps (is that a white T-shirt someone for the canning??), and the great pics (red vs orange, very helpful). The stash of bottles is also swoon-worthy. Btw, I just read that most tomato sauce adds 2.5 tsp of sugar per bottle, so you’re avoiding all that. No wonder your boys prefer the taste of this – it’s the real thing. I want to try – thanks for posting…
