oregon berries two purple figs marion blackberry jam


2 cups frozen Marionberries
1 cup sugar
1 cup water
1 cinnamon stick broken into two
6 cloves whole
Pinch of salt
½ teaspoon gelatin in 1 tablespoon water


Step 1
Use a cheesecloth and wrap the whole spices in it, tying it well.

Step 2
In a large pot add in the berries, sugar and water, mix those well.

Step 3
Use a potato masher to slightly mash the berries or leave them whole if you prefer a chunkier blackberry jam.

Step 4
Place the pot over medium high heat and as soon as the sugar starts to dissolve, add in the spices in cheesecloth.

Step 5
Drop the heat to medium low and stir the jam frequently for about 20 minutes until it starts to thicken. The majority of the water should have been evaporated and the flavor of the berries should have intensified.

Step 6
Remove the cheesecloth with the whole spices and stir in the gelatin or pectin if using.

Step 7
Immediately turn off the heat and put the jam in a glass jar. Keep the jam stored in the fridge for 2-3 months and enjoy!
