Berry jam: a novice's first attempt
Corinna Borden | Contributor
Last fall we canned tomato sauce for the second year in a row, and we did applesauce as well. I have learned the trick of the popping metal top and the stove was not that hot. So this weekend, inspired by the gorgeous fruit at Makielski's Berry Farm (site of my most recent Farm to Fork visit), I made blackberry jam - and I used their raspberry honey for the sweetener.
I learned several important lessons.
#1 - I need a bigger stovetop or I need to make smaller batches.
It was a precariously balanced stovetop with two water sterilizations going for the glass jars, the large black canning pot, and the pot for the cooking of the fruit.
#2 - When the recipe says “Measured Ingredients: 4 cups mashed fruit” - read it twice.
I had measured out fruit, then mashed it, then put in the lemon juice, and then read that it is “mashed.”
#3 - Don’t wear a white shirt while making blackberry jam.
Indeed.
#4 - The whole house is infused with sweet warm berry goodness - absolutely divine.

I followed the recipe included in the Pomona's Universal Pectin, which I purchased from Downtown Home and Garden. Based on my experience with applesauce last fall - I thought I did not need pectin. But I was kindly corrected by Mark Hodesh, owner of Downtown Home and Garden, who shared that apple and quince are the only two fruits that have high enough pectin to gel - otherwise one must augment. According to Wikipedia, guavas, plums, gooseberries, and oranges can be added to the high pectin list.
I am happy there are more weeks of blackberry, cherry, blueberry, and raspberry picking because I would like to experiment further. I am curious to hear from those of you who have done this before - aside from not wearing a white shirt, are there more things I should watch for as I dabble?
This is the recipe I followed (well, except for the fact that I put in enough lemon for 12 cups and only ended up with 9 cups of mashed fruit). It did gel and it tastes like blackberries.
• Wash and rinse jars; let stand in hot water. Bring lids and rings to boil; turn down heat; let stand in hot water. • Measure mashed berries into pan with lemon or lime juice (4 cups of mashed berries for every ¼ cup of lemon or lime juice). • Add proper amount of calcium water (an addition that Pomona’s includes that helps to activate their pectin, 2 teaspoons). • Measure 1/3 cup honey and mix in 2 teaspoons of pectin. • Bring fruit to a boil. Add pectin-honey; stir vigorously 1-2 minutes while cooking to dissolve pectin. Return to boil and remove from heat. • Fill jars to ¼ inch of top. Boil 10 minutes. Check seals - lids should be sucked down. Lasts about 3 weeks once opened.

Yes, just wash your jars in the dishwasher, and fill them when they are still hot. This isn't technically sterlizing them, but jars do not need to be sterilized before canning if they will be filled with food and processed in a boiling water bath canner for 10 minutes or more (most jams are processed for 10 minutes). Jars that will be processed in a boiling water bath canner for less than 10 minutes, once filled, need to be sterilized first by boiling them in hot water for 10 minutes before they're filled. But you could use your canner for that. I can a lot, and I don't think I've ever canned anything that processed for less than 10 minutes.

Hint - use your canning pot to sterilize your jars. Then you don't have to heat up 2 large pots of water. That's how I do it. YOu can also sterilize your jars in the dishwaher.

I also made strawberry jam for the very first time this summer from my own berries. I discovered that the amount of whole berries the recipe said would yield the right amount of mashed berries was not accurate: too few. Fortunately the recipe indicated how many cups of mashed berries were needed. I also discovered that a stove with two big burners would be a big improvement over mine with only one big burner.
