Step 1

Put a small plate in the freezer.

Step 2

In a wide pot mix the berries, sugar, lemon juice, and bourbon and set aside for about 30 minutes or until the sugar and bourbon has started to breakdown the blackberries.

Step 3

Bring mixture to a boil over medium high heat stirring occasionally.

Step 4

Reduce temperature to medium and simmer until mixture begins to thicken, about 20 minutes. Keep stirring so nothing sticks to the pot.

Step 5

Once the mixture starts to thicken, put a tablespoon of the mixture on the plate in the freezer and freeze for 1 minute. Test the gelling point of the jam by pushing your finger up against the cold jam and if it done it will wrinkle.

Step 6

Remove from heat and let cool.

Step 7

Pour the jam into jars and they will keep for around 2 weeks.
