Ingredients

4-5cups Blackberries
1cup SugarMay add 1 more cup of sugar if desired
2tbsp cornstarchMay be omitted, helps to thicken
2tbsp Lemon Juice

Instructions

Add blackberries to a large saucepan and heat over low heat. Mash the blackberries with a masher or use a wooden spoon to press the blackberries against the side of the pan.
Stir in one cup of sugar plus 2 tbsp of lemon juice and continue stirring the blackberries over low heat. The juices may foam, but continue stirring to keep the foam down. In this low sugar recipe, you may use 1 tbsp of blackberry juice mixed with 2 tbsp of cornstarch to help thicken the jam more quickly. You may also add more sugar to thicken the jam (but it will make the jam sweeter). If you desire the low sugar version, patiently cook the juices down. It may take up to 30 minutes to cook the juices down for this low-sugar version.
The blackberry juices should thicken into a gel. The consistency will look thicker and the jam will appear more glossy. You can test for doneness by putting some jam onto a cold plate to see if it appears to thicken. Let the jam cool before pouring it into a jar. Enjoy!
