I use a bunch of fresh blueberries, about four cups to be exact. I also use lemon juice, cinnamon, and white sugar. You can use raspberries, huckleberries, or strawberries.

If you don’t have lemons, use lime juice, or a bit of an acid juice, like pineapple or orange. As for the sugar, I like white sugar, but you can use caster, brown, molasses, or honey.

To cook this will take about 30 minutes, as the mixture gets hot and thick. I usually let everything boil until the temperature reaches 220 degrees F, and I stir continuously to prevent scorching.

I should also remind you to leave enough headspace for the jam to expand. As my grandma always told me, clean the bubbles, and then seal your jars.

Once my jars are cool, I store them in the refrigerator. This jam is good to go for around 10 days, so enjoy it every day you can!

I hope you enjoy my grandma’s blueberry jam that I have made many times and continue to do so every chance I get.
