Prepare the Jello: Start by following the package instructions for each jello flavor—kiwi, lemon, blueberry, and raspberry. Mix the gelatin with hot water, stirring until fully dissolved. Pour the jello into molds or shallow containers for even layers and allow them to set in the refrigerator for at least 4 hours, preferably overnight, until firm and ready for cutting.

Make the Biscuit Base: Line the base of a 22 cm springform pan with baking paper to prevent sticking. In a bowl, crush the digestive biscuits into fine crumbs. Combine the crumbs with melted butter and brown sugar, mixing until well combined. Press this mixture firmly into the bottom of the pan to create an even base, then refrigerate for about 30 minutes to set.

Soak the Gelatin Sheets: In a small bowl, soak the gelatin sheets in cold water for approximately 10 minutes until soft. Meanwhile, in a saucepan over medium heat, warm the pineapple juice, adding in the sugar. Once the sugar has dissolved, remove from heat and stir in the soaked gelatin until fully melted, allowing the mixture to cool slightly before using.

Prepare the Cheesecake Filling: In a large mixing bowl, whisk together the sour cream, heavy cream, and cream cheese until fluffy and smooth, which should take about 3-5 minutes. Once well combined, add the cooled pineapple juice mixture and freshly squeezed lemon juice, stirring gently until everything is evenly blended to create a rich and creamy filling.

Combine the Jello and Filling: Take the set jello layers from the refrigerator and chop them into small cubes using a sharp knife. Gently fold the jello pieces into the cheesecake filling mixture, ensuring that the colorful cubes are evenly distributed. Pour this beautiful mixture over the chilled biscuit base in the springform pan, smoothing out the top with a spatula.

Set the Cheesecake: Cover the springform pan with plastic wrap and return it to the refrigerator. Allow the Terrazzo Cheesecake to chill and set for at least 4 hours, but preferably overnight, to ensure it firms up perfectly.

Serve and Enjoy: Once set, carefully remove the sides of the springform pan. Slice the cheesecake into wedges and admire the vibrant terrazzo layers. For a finishing touch, consider serving with fresh fruit or a drizzle of fruit syrup.
