You can can! (home canning tips and tricks)

Sep 15, 2010 | Canning, Tips and Tricks

As we shift seasons, and — dare I mention it — winter draws closer, it’s nice to plan ahead to save some of your delicious organics for when there’s snow on the ground.

Many people enjoy spending  a cool fall day (or two) doing some canning. The windows can be open, so even if your kitchen escapades heat up the house you have a lovely breeze coming through to cool you off.

Hopefully the overview below is informative and helpful to you in either getting started, or in giving canning another go if you’ve tried it before!

What do you need?

  • A canner (many people use a big pot and the boiling water method, though it is often recommended to get a pressure canner)
  • A canning rack (this is what you sit your jars on in the pot)
  • One or more funnels (for pouring your concoctions into the jars)
  • Jar lifter (very handy in order to get those jars in and out of the hot HOT water)
  • A jar wrench (to loosen the lids after canning — so you can eat your delicious concoctions!)
  • An assortment of jars, tops, and lids

Then what do I do?

Although the cooking times and packing instructions will vary depending on what you are making, there are some basic guidelines you’ll need to follow, no matter what you’re preserving.

1. Sterilization. You must sterilize your jars and lids by boiling them! (Carefully review each recipe to determine how and for how long to sterilize). Tops and lids should be used once and then you must use new ones the next time you can. Jars are okay to reuse as long as they are sound.

2. Hot Stuff.  What’s going into the jar must be HOT. The jars will be hot (you just sterilized them, good job!) and in most recipes the food itself should be bubbling hot on the stove when you go to put it into the jars. If the jars are being packed cold (like with pickles) the pickling liquid you’re using should be boiling hot.

3. Acidity. One of the keys to successful canning (read: safe to eat, no bacteria!) is to follow the recipe/directions closely. In addition to the temperature of both the ingredients and the hardware, the amount of acid in the recipe is key. It is VERY important to follow each recipe and use the exact amount of the exact ingredients and cook at the exact temperature for the exact length of time. Got it? EXACTLY! 🙂

4. Boiling Times. Your goal is to ensure that NO bacteria survive the canning process. Jars must seal tightly, there needs to be enough space remaining in the jar after you’ve filled it to ensure that the food has room to expand in the heat without pressing on the jar tops and lids (this can break the seal).   Your jars need to be properly sealed and boiled for the amount of time required (and in the method described in your recipe) in order to ensure they’ll be safe to consume when you are done.

5. Easy Does It — Cooling Off. Space out your finished product in a low traffic area so air can circulate around and cool off the jars. Keep out of cold breezes and most certainly do not put them into your fridge (or, for goodness sake, your freezer) to speed up the cooling process.  You don’t want to break any of the jars! Remember to tuck them away somewhere as they cool so no one gets burned on the hot containers.

6. “Pop”. Did you hear a popping noise as your jars cool and seal? If the tops do not curve in nicely, the seal hasn’t work, or hasn’t held. This becomes your ‘tester’ jar — keep it in the fridge and use it right away.

7. Storage. Store your delicious finished product in a cool, dry, dark place.  Canned goods make lovely hostess gifts, tie them up with a little ribbon and pop on a custom label (easy to make with labels you can get online or at craft or office supply stores).

8. Be Sure! If anything about your jar seems off, if the lid is bumped out, slightly askew or if you notice mold, bubbles, cloudiness, bad smells, or oddly discoloured food when you open a jar, don’t even think about trying it! Throw away the lids and seals, and dump out the contents.  You can reuse the jar without concern.

So those are some starter points –for more information, Eat Right Ontario has a great FAQ page about canning that will answer any questions a new canner might have.  Check it out for all the basics and tips to get you started. You might also want to visit’s Canning Site.

If you like to have a book to work from, my research pointed me to one book over and over — Ball Complete Book of Home Preserving.  And Ball also has a fantastic, informative website — pop over to learn everything you need to know about home preserving, they have a raft of recipes as well.

Good luck with your preserving — if you have a favourite recipe to share with us please post it as a comment or email me and I’d be happy to share it with everyone on the blog!
