A few years ago I started getting into canning. I blame Meijer entirely because they put up a beautiful long shelf display devoted to canning, and it totally suckered me in. I bought all the stuff (there’s quite a bit of stuff you need) and just dove into it.
And, now, I can happily say I’m a full blown jamstress. Kudos to Gilmore Girls for that word, btw!
I got this recipe from Food in Jars, the best canning site out there in my opinion. I adapted this just by keeping the seeds in my blackberries.
If this will be your first attempt at jamming and canning, my advice is that you do your research. It can be a bit overwhelming the first time you attempt it! **Milady Note: I gave some to my Aunt Janie, so thanks to her for taking this awesome beauty shot!**
6 cups blackberry pulp (8-9 cups of berries, mashed)
4 cups sugar
2 teaspoons cinnamon
1 teaspoon freshly grated nutmeg
1 lemon, juiced and zested
1 packet liquid pectin (half the box)
Prepare your jars, start your lids simmering and bring your canning pot to a boil.**Milady Note: I always end up preparing a lot more jars than I end up using. It’s best to err on the side of having too many available jars!**
In a large, non-reactive pot (stainless steel or enameled cast iron), combine the sugar and fruit pulp and bring to a simmer. Add cinnamon, nutmeg and lemon zest/juice and stir to combine.
Let the mixture reach a boil, stirring frequently to prevent it from boiling over. When the mixture appears to be thickening a bit, add the pectin and bring it back to a roiling boil.
Let it boil vigorously for at least five minutes to activate the pectin. Before removing from the heat, check the set using the plate or spoon test to ensure that the jam will firm up when cool.
Fill your jars with the hot jam, wipe rims, apply lids and rings and process in a boiling water canner for 10 minutes.
Remove from canner and allow the jars to completely cool on a dishtowel-lined counter top.
Canned jam is good for a year. Remember to label your jars with the date! **Milady Note: Ball makes labels that dissolve in water. They are magical!**
