It's true! You can be creative with cooking. But canning...well, you don't want to mess with that ingredient list. In order to preserve anything safely, you have to follow the directions to a T. I'm guessing that's why canning is intimidating to so many people.
Let me state here and now that canning is fun...canning is rewarding...and canning is very do-able. You can do it! I promise!
This is going to be a rather long blog post because canning is...well...complicated. Not hard...just complicated. If you've never canned before, I suggest doing it with someone for your first time so that you can get the hang of it. If you know me, let this be an invitation to come and invade my kitchen. If not, I'd love to meet you!
Before you even think about canning, there are some things you need. I'm talking about supplies...
You'll also want some tried and true recipes. I tend to trust those published by the canning companies over those that were invented by somebody's grandmother in the 1920s. Scientists have verified the safeness of Ball's canning recipes. I'm not so sure they've done the same for grandma's.
These are my favorite canning books. There's so many recipes featured, you won't even miss grandma's creation!
I've discovered that the key to successful canning (besides having the equipment and following the recipe to the T) is getting everything prepared before cooking a thing. So, I get my big water canner and fill it up with enough water to cover the tops of whatever jar I'm using by at least an inch. Place it over high heat - you want to get it close to boiling by the time you are ready to put your jars in, and it takes quite a while to heat up.
Then I wash everything else. It doesn't matter if you washed it before you put it in the box one month earlier. It doesn't matter if you just got it out of the shrink wrap. You must freshly wash it.
What's all that stuff in the above picture, you ask? Well, I'm hoping you are familiar with jars (those glass things on the right). I always prepare one more jar than my recipe says I'll need (just in case). To the left of the jars, we have the lids (the ones with the brand names on them) and caps (these ring-shaped items go over the lids to keep them in place). To the right of the lids is a blue funnel, for pouring your food into the jars. At the bottom of the picture are two more blue items - a magnet and a quasi-measuring stick. I'll demonstrate those in a minute.
Put your jars into a large saucepan and cover with water. Turn on the heat and bring the water to a simmer (not a boil). You want the jars to be hot when you pour your hot food in or they might crack. If you can't fit all the jars in at once, that's okay. You can rotate more in during the process.
Do the same thing with your lids and caps...remember, you don't want to boil them! Just get them warm.
Then you are going to want to prepare your counter-top with the following items: a trivet (to put your hot saucepan of food on), your funnel, your magnet, your quasi-measuring stick, tongs (to get the jars out of the hot water), and finally a washcloth. The washcloth should be dry with one dampened corner...trust me.
Now it's time to start cooking! I made blueberry-lime jam from Ball's Blue Book of Preserving. My husband loves blueberries, and this recipe sounded just weird enough to try.
Pull out all of the ingredients and get them prepared (remember - this is science, not a time for creative experimentation). Most jam recipes are pretty basic - this one called for sugar, lime juice, lime zest, pectin, and, of course, blueberries.
I went ahead and zested the lime and measured out the sugar...
The next step was crushing blueberries. The recipe says to crush the blueberries one layer at a time. So I put a layer of blueberries in a glass dish and got out my potato masher.
As you can see, that didn't work too well for me...
My blueberries are hardly crushed. I suppose I could have gone at it for a little longer, but I resorted to an easy trick my mother taught me...the Salad Shooter (or food processor, if you have one).
Whole blueberries in, crushed blueberries out. It worked quite nicely and very quickly.
The next step is to combine the crushed blueberries and the box of pectin together in a large saucepan.
Bring this mixture to a boil (stirring constantly), and then add your sugar. Aren't you glad you pre-measured your sugar?
Stir the sugar until it's dissolved...
...then add the lime juice...
...and the lime zest.
Then return this mixture to a boil. Don't settle for a mediocre boil...you know, a bubble here, a bubble there. You want a full rolling boil. By that I mean that you shouldn't be able to stir it down...it should keep on boiling, no matter how hard you stir. You need to hard boil this for one full minute, stirring the whole time.
At this point, your stove will look something like this...
Yes, it's true...canning will take over your whole kitchen.
Once your jam has boiled for one minute, you need to remove it from the heat. Place it on that trivet that you prepared for this very occasion.
Then, you need to skim the foam off of the top and throw it away. Now, I know, I know...it seems like a waste. But really, it's not. The foam ruins the aesthetics of your jam in the jar, and it doesn't taste good anyway! Don't believe me? Try it...if you like it, you can always stick it in some tupperware and put it in the fridge. But whatever you do, don't stick it in the jar.
Now grab your tongs and pull a jar out of its hot water bath.
Empty the water out of it (I would hope that would be an obvious step...).
And use your funnel to fill it up with jam.
Here's where the quasi-measuring stick comes in. The recipe says to allow 1/4 inch headspace at the top of the jar. Since we are following the recipe to a T, we need to measure. And the stair-step looking side of the measuring stick has those measurements printed on it. We find the right one and use it to help us get the exact headspace needed.
Then we turn the stick around and use the other side to get out air bubbles. Simply run it down the edge of the jar on a few sides.
And now that we've made a mess, we're going to need our washcloth. Take the dampened corner and very carefully clean the rim of the jar. This is important - if there is anything on the rim, it might not seal (and that would not be safe).
Once you get the lid cleaned off, use your blue magnet to reach into the hot water and get out a lid...
...and place the lid on top of the jar.
Then use your magnet to reach back into the water to pull out a cap...
...and place it on top of the lid.
You'll be glad you had that magnet...those suckers are hot!
Speaking of hot...the jar will be hot by this point, too. So, don't try to twist on the cap with your bare hands...that would be silly. Instead, use that washcloth to help you out (that's why we only dampened a corner). You only need to get it fingertip tight.
Using your tongs, place the jar into the hot water canner.
And repeat until you've filled all the jars. Now let's say that you get down to the very last bit of jam and don't have enough to fill a jar. No worries - just stick it in a tupperware dish and pop it in your fridge. But never, ever process a jar without the amount of jam the recipe calls for. Remember...this is science!
After you've got all your jars in the canner, put the lid on and bring it to a boil.
Once the water has reached a rolling boil, the processing can commence. Each recipe is a little different - this one says to process for 15 minutes. Some say 10. Some say 20. The important point is to do what the recipe says and don't start your timer until the water has reached a rolling boil. That means you might have to lift up the lid and peek your head in to check...this is perfectly acceptable.
After you are done processing, use your tongs to lift each jar straight...I mean straight...out of the canner. No waving it around. Lift it straight. Got it?
Continue to keep the jar upright...
And then set it upright on wire racks (or somewhere where it can breathe).
Leave about 2 inches between each jar as they cool. And then leave them. Don't worry about any water collected on the lid...leave it. Don't turn it upside down to see what it looks like...leave it.
Leave them for a full 24 hours. No cheating! This is science!
The next day, you want to take the caps off and test your seal in two ways. The first - press your finger on top of the lid. If it doesn't pop, you are good (just like you test jars you buy from the store).
Second - put your fingers on either side of the lid and gently pull up. If it doesn't come off, you're good.
The final step...write the name of the food and the date on the lid of the jar. I always thought this was silly...I'd remember, right? But then I didn't remember once. I've learned my lesson.
If sealed properly, your jam can be stored in the cabinet indefinitely! But don't forget to put at least one jar in the refrigerator...you'll want some of this stuff for your tea and bread. It was delicious! :-)
