Great Canadian Food Experience; Preserving Heirloom Tomato Sauce

Great Canadian Food Experience; Preserving Our Canadian Food Tradition by Canning Heirloom Tomato Sauce

Canned Tomato Sauce

This time of year I’m still neck deep in tomatoes. We grow them all summer, then as we pick them I make notes, take photographs, and try to stay organized before ripping them open to start fermenting the seeds. By the time I’m saving seeds I’m quite attached to each and every tomato and it’s impossible for me to simply compost the “waste” fruit.

Heirloom Tomatoes

Ontario summers are nice and hot and our Februarys are just so dreary.  This makes many of us go to a great deal of bother to preserve some of the summer produce for the gray days ahead.  So as I scoop our the seeds of each heirloom tomato, I run them through the grinder and toss the fruit into the slow cooker and slowly and easily make tomato sauce to enjoy in the cold.

 Cutting Tomatoes

Tomatoes through Kitchen Aid Grinder

Simply put your cored, or in my case, gutted tomatoes though a food grinder, mill or food processor straight into your slow cooker. You can add salt and dried herbs if you like.  You can even roast your tomatoes in the oven before hand.  Once the slow cooker is full, turn it on to low heat and walk away, or go to bed if you cook at night like I do. 24 hours later your sauce should be a gorgeous shade of red and ready to can.

Following Bernardins’ guidelines for Basic Tomato Sauce and simply changing the cooking method is a perfectly safe method of putting up tomatoes:

I follow the same method when canning whole tomatoes.  Any ugly or accidentally crushed ones get put aside and then turned into sauce at the very end.

When it comes time to process your jars, add the right amount of lemon juice and process in a water bath for 45 minutes. Full instructions and amounts can be found here:

If you are worried about the acidity level of heirloom tomatoes over the standard romas you can use mostly paste varieties, add more lemon juice or citric acid, or simply eat it right away.

Make Tomato Sauce in Slow Cooker

Preserving seeds and helping with seed diversity has led to making and canning about 40 jars of pasta sauce. I have to say it’s hard not to just eat it all right now so the only issue is having enough left to last through our cold Canadian winter.

The Great Canadian Food Project began June 7 2013. As we share our collective stories through our regional food experiences, we hope to bring global clarity to our Canadian culinary identity

How to: Freeze and Peel Tomatoes for Easy Preserving and Winter Hoarding

Monday, August 20th, 2012

The tomatoes are starting to roll in. It’s always exciting at first, those first tomatoes. Grown by spring rain and summer heat.  Quickly though, full on tomato panic starts to sets in. Where do you put them all? How can you prevent buying some in December when there are so so many right now? Canning is nice, but not always practical (especially when you are having a baby right at canning time. I clearly didn’t plan this very well).

Freezing is one of my favourite ways of preserving some of August’s glut of tomatoes to enjoy cooked throughout the winter.

Start by washing your fruit and then slice a simple x through the skin on the bottom of each tomato. This will keep them from splitting and make them easy to peel when cooking in a few months.

Next I lay them flat in a pan or tray and slide them into the freezer.  A cookie sheet works perfectly as does a pyrex or enamel pan.

When they’re frozen it’s time to bag them up.  They should stay separate so you can use exactly as many as you want. We keep giant resealable bags in the freezer and throw a few in when cooking tomato soups or sauces.

If you want to peel your tomatoes, either after they’ve been frozen or before, here’s how we do it.

Boil a pot of water on the stove and plunge your “x”ed tomatoes into the water for up to a minute. Remember we’re blanching tomatoes not cooking them.

Then quickly plunge the tomatoes into cold water.  You can scoop them out with a spoon but I like using a steamer basket and plunging the whole thing.

Next you simply slide them out of their skins. Easy Peasy! (unlike those pesky peaches last year). As Well Preserved points out, if you’re going to peel more than one pot worth you will want to wear gloves. The acidity of the tomatoes will really wreak havoc on your skin.

You’ll be left with a perfect pile of peeled tomatoes.  You can either peel from frozen or peel then freeze, what ever you prefer. You can also peel your tomatoes this way and then can them.  Freezing is simply the easiest way to preserve tomatoes for the winter when you can’t solar oven, sun dry, dehydrate, or can.
