Help! I'm in a JAM!
Alright, alright. Just teasing. But I AM in a jam--literally! But it's a very sweet tasting jam, so I don't mind.
When we moved to our house five years ago, we knew we wanted to plant blackberries. They are tough plants--just the kind I need. They don't kill easily, and even if you WANT to kill them off, it's well nigh impossible to do. That's the plant for me! Our friends from California where we used to live think we are crazy, because back there the blackberries grew wild EVERYWHERE. You hacked at them to keep them from taking over your yard--literally! And whenever you wanted fruit, you just went out and picked.
Not so in other parts of the country. So ever after, whatever state we moved to, we planted blackberries in our yard. While we lived in Texas, I found a variety that was very much "Texas Tough," which is just what I needed. No coddling, no spraying, no fussing. Just throw them in the dirt and they grow. O.K., the first year I did spray them with water occasionally. But no watering after that--really, they need to survive my lack of care! So, when we moved to THIS state, I actually mail ordered the very same Texas bread blackberry root cuttings--ordering them from a plant nursery in Texas. Fortunately for me, they seem just as happy growing in this state as they did in Texas.

Blackberries need around three years to start producing. The third year, we got "some," but we knew the harvest the following year would be GREAT. And it was. For the deer. We had deer eating the blackberries in California, but there was always PLENTY for us as well. Guess there was just more plants growing wild in that area, because we never noticed a lack of berries for us. But here in our yard we sure did. Last summer we saw scores of blackberry blossoms, and new it was going to be a GREAT harvest. Our mouths watered as we watched the berries turn a deeper color. We got to eat a few. But then would go out to pick and the berries had turned invisible. They just. weren't. there. But there WERE plenty of little green stems sticking out with nothing on the end of them. DEER. Those dear little deer. I don't mind sharing some with the deer, really. But they did not exactly leave any to share with us.
So this year we knew we needed to do something, but what? The bushes are not really planted in an area where they can be easily (or cheaply) fenced. Besides that, deer can jump fences--they have even been noted to jump six foot fences upon occasion! Dogs help, a lot. But our dog does not run free in the front yard since it IS unfenced, so she would only be helping to keep any deer out of the back yard. Finally a friend of mine suggested that we try bird netting. I didn't have much hope, but it was worth a try. Well, so far, so good! Maybe the netting just is kind of scary to the deer, so they aren't messing with it too much.
SO. Back to my jam. First, you need to start with some blackberries rescued from the deer!
I follow directions in the low sugar pectin box. It tells how much crushed fruit for each variety, and how much sugar to measure out. You take a little bit of that sugar, and mix it with the pectin and that gets stirred in with the crushed fruit right away. You also have to add in just a tiny bit of margarine, to keep it from over foaming. I forgot once--and was amazed at how foamy it was!!! The directions say to add in 1/2 tsp. I personally do not want to add fat to my jam, so I put in probably closer to 1/4 tsp. and it seems to work just fine. I asked my chemist husband about it, and he said it worked as a surfactant. He said I could also use soap, if I didn't want to use the margarine. I think I will continue using the margarine!
Anyway, so you take the crushed fruit with the sugar/pectin mixture and the margarine and this gets brought to a boil over high heat. You have to stir it constantly, and I will warn you that it will splatter hot jam at you, so I always wear oven mitts when I am stirring jam. After it has come to a rolling boil, you add the rest of the sugar that you have already measured out and then stir it as it comes back to a boil again. Things can get tricky at this point as you need to move fast, so have everything laid out and ready that you are going to need.
I keep my clean, washed jam jars in hot water in the sink, where they wait for my jam to be boiled and ready.
I have already boiled my lids, and they are sitting in their hot water just waiting on the counter where I will bring my hot jam.
Then you ladle the hot jam into each jar, filling it to within 1/8th inch of the top. Next you wipe off any jam that spilled onto the top part of the jar, and place the lid on screwing the band tight--but not over tight, just hand tightened.
I wish I had a picture of the next step, but my computer messed it up so we will have to do without. But I use the "inversion" method for sealing my jars. After the lids are hand tightened, you literally flip the jam jar upside down so it is sitting on the lid part. You let it sit this way for five minutes, then turn them back right side up. As the jars cool, you will start hearing a "pop" sound, which is a VERY happy sound, as it is the sound of the jars sealing. If for some reason a jar does not seal, you can either stick it in the fridge to use right away, or you can water bath can it to get it to seal.
And there you have it--my assorted sizes of jam jars! I was scraping all around in my cupboards for more jam jars to fill--almost did not have enough, as this canning session filled 27 jars of jam!
Praise the Lord! A gift from above. Only He can make those berries grow, I cannot. We sure are going to enjoy this jam through the next year! If you have never tried canning before, jam is a great item to start with. You can even make freezer jam, which is even easier as you get to skip all the boiling and sealing part. Freezer jam is uncooked jam, and ends up with a fresher taste, though it will also be not as firm and a little on the runny side. Great to use as a fruit syrup on waffles and pancakes though!
If you don't have fruit growing in your yard, go check out some farmer's markets. I was even able to purchase strawberries at a discount grocery store this year cheap enough to make some of it into jam.
Hope I helped give you some ideas for summer canning! It is so nice to enjoy frozen fruit or jam during the rest of the year, when it is not in season.
