Blackberry-Swirled Cheesecake Ice Cream

Cheesecake Ice Cream

1. Combine all ingredients in a blender and blend until smooth. Transfer to an airtight container and chill in refrigerator for several hours, preferably overnight.
2. Just before churning, whisk mixture to smooth out again. Churn in an ice cream maker according to manufacturer's instructions, slowly adding in graham cracker crumbles once thickened, about 3-5 minutes before churning is finished. Use a spoon if needed to help mix crumbles in completely.
3. Layer ice cream with blackberry sauce in a freezer-safe container and swirl briefly with a knife or offset spatula. Cover container with a lid, or wrap tightly in plastic wrap and place in a freezer-safe, zip-top bag. Freeze for at least a few hours before serving.

Blackberry Swirl

1. Toss blackberries and sugar together in a medium saucepan set over medium heat. Bring to a simmer, crushing blackberries into smaller bits as they soften.
2. Meanwhile, whisk together water, lemon juice, and corn starch to form a slurry.
3. Remove berries from heat and, while stirring, slowly add slurry. Return to medium-high heat, stirring occasionally, and bring to a boil. Reduce heat to a simmer and simmer for 1 minute.
4. Remove from heat and stir in creme de cassis. Transfer to an airtight container and refrigerate for several hours, or overnight. Stir to loosen and smooth out before adding to ice cream.

Graham Cracker Crumble

1. In a bowl, whisk together the crushed graham cracker, pastry flour, brown sugar, and salt. Add the melted butter and mix in until the mixture is crumbly and all of the dry ingredients are coated in butter.
2. Heat a large skillet over medium-high heat. Transfer crumble mixture to skillet in a flat layer and cook for about 5-7 minutes, until golden-brown, watching closely and stirring frequently to prevent burning. Remove from heat and transfer to a tray or sheet of parchment to cool completely before adding to ice cream. (Note that crumble with get crunchy as it cools.)
