Start by crushing the biscuits into fine crumbs, making sure there are no large chunks. Mix them with melted butter until the texture resembles wet sand. Press this mixture firmly into small discs or into the base of your molds and chill until set.
In a bowl, beat the cream cheese and powdered sugar until smooth and creamy. Add lemon zest and juice, mixing until fully incorporated for that fresh citrus flavor. Fold in whipped cream gently to keep the filling light and airy.
Sprinkle gelatin over water and let it bloom for a few minutes. Heat it gently until dissolved, then mix it into the cheesecake filling. This step helps the domes hold their shape once chilled.
Pour the cheesecake mixture into silicone dome molds, filling them halfway or slightly more. Place the prepared biscuit base on top and press gently. Freeze the molds for several hours until completely firm.
Cook raspberry puree with sugar until slightly thickened and smooth. Add gelatin and glucose syrup, stirring until glossy. You can add a drop of red coloring to enhance the ruby effect.
Remove the frozen domes from molds and place them on a rack. Pour the glaze over each dome, allowing it to coat evenly and drip down the sides. Let them sit until the glaze sets into a shiny finish.
Transfer the glazed domes to the fridge for about an hour before serving. This helps the texture soften slightly while keeping the shape intact. Serve chilled for the best taste and presentation.
