Step 1

Preheat oven to 400 degrees F. Line a baking sheet with parchment paper. Roast blackberries for 10-15 minutes, until they start to break down and lose some of their juices. Remove and set aside.

Step 2

In a large pot over medium-low heat, whisk the remaining ingredients together. Continue to whisk and cook for about 10 minutes, until the mixture begins to simmer. It should thicken enough to coat the back of a spoon. Remove from heat and place in a heat safe bowl. Transfer to the refrigerator to cool.

Step 3

Once the mixture is cool, pour it into your ice cream maker and follow it's directions. In the last 5 minutes of churning, throw in the blackberries.

Step 4

Transfer to a freezer safe dish and freeze until set. Serve with fresh blackberries.
