BLACKBERRY-RIPPLE LIME CHEESECAKE

Steps:

• Position oven rack in the middle of the oven; preheat oven to 350°.
• Generously butter the bottom and sides of a 9-inch springform pan.
• Make the crust: pulse the pecans, flour, and sugar in a food processor until the nuts are finely ground.
• Add the butter and pulse just until combined; press the crust evenly over the bottom and 1 inch up the sides of the pan.
• Bake for 10-12 minutes, until light brown.
• Transfer to a wire rack and cool completely; decrease oven temperature to 300°.
• Make the filling: mash the blackberries and sugar together in a medium saucepan with a pastry blender or fork.
• Cook over medium heat, stirring occasionally, until the berries begin to release their juices.
• Stir in the cornstarch, bring to a boil over med-high heat, stirring constantly, and boil for 1 minute.
• Pour the puree through a coarse strainer set of a small bowl, pressing hard on the solids to extract as much liquid as possible.
• Refrigerate, tightly covered, until thoroughly chilled.
• Using an electric mixer on med-high speed, beat the cream cheese in a bowl for about 2 minutes, until light and fluffy.
• Gradually beat in the condensed milk, zest, lime juice, and vanilla, scraping down the side of the bowl as necessary.
• Decrease speed to medium and add the eggs one at a time, beating well after each addition; pour the batter into the pan.
• Transfer the blackberry puree to a small glass measure; drizzle it in a spiral pattern over the batter, then swirl with a table knife through the batter to marbelize it.
• Bake for 55-60 minutes, until the cheesecake is puffed on the sides and still slightly jiggly in the center; let cool on a wire rack.
• Refrigerate the cheesecake, tightly covered, for at least 8 hours, until thoroughly chilled and set, of for up to 2 days.
• To serve, run a sharp knife around the edges of the pan to loosen the cake and remove the side of the pan.
• Cut the cheesecake into thin wedges with a sharp knife dipped into hot water and wiped dry after each cut.
