Prepare Jello Layers: Begin by making your jello according to the package instructions, using assorted flavors like kiwi, lemon, blueberry, and raspberry for that vibrant terrazzo effect. Pour each flavor into separate molds and refrigerate overnight to allow them to set completely into firm layers, ensuring they will hold their shape when added to the cheesecake.

Make the Cheesecake Base: Grease a 22 cm springform pan to prevent sticking. In a mixing bowl, crush digestive biscuits until finely ground, then combine them with melted butter and brown sugar. Press this mixture evenly into the bottom of the pan to form a firm base, and place it in the refrigerator to set while you prepare the cream cheese filling.

Soak Gelatin for Cream Filling: In a small dish, soak the gelatin sheets in cold water for about 5 minutes until they soften. Meanwhile, bring pineapple juice and sugar to a gentle boil in a saucepan over medium heat, stirring until sugar fully dissolves. Remove from heat and stir in the soaked gelatin until it completely dissolves, then let the mixture cool slightly.

Whisk Cream Cheese Mixture: In a large bowl, whisk together sour cream, heavy cream, and cream cheese until the mixture is fluffy and creamy, which should take about 3-5 minutes. Gradually mix in the cooled gelatin mixture and freshly squeezed lemon juice to taste, ensuring everything is well blended and smooth for your Terrazzo Cheesecake filling.

Assemble the Cheesecake: Carefully chop the set jello into bite-sized pieces. Gently fold the jello cubes into the cream cheese mixture, creating a marbled effect for that beautiful terrazzo look. Spoon this vibrant filling over the chilled biscuit base in the springform pan, smoothing the top with a spatula, then refrigerate for at least four hours, or preferably overnight, to fully set.

Serve and Enjoy: Once set, carefully run a knife around the edges of the springform pan and release to reveal your stunning Terrazzo Cheesecake. Slice into portions and serve chilled, optionally garnished with fresh fruit or mint leaves for an elegant touch. Delight in the creamy texture and colorful layers that are sure to impress your guests!
