White Christmas Terrazzo Terrine

Colored Jelly Layers:
- 1 packet (85g) Apple (Green) jelly crystals
- 1 packet (85g) Watermelon (Light Red/Pink) jelly crystals
- 1 packet (85g) Strawberry (Deep Red) jelly crystals
- 750 ml (3 cups) boiling water (divided into 250ml per packet)
White Cream Base:
- 1 can (395g) sweetened condensed milk
- 1 cup boiling water
- 2 tbsp powdered gelatin (unflavored) dissolved in ¼ cup cold water
The Crust & Top:
- 1 packet plain rectangular biscuits (like Petit Beurre or Marie biscuits)
- Optional: Extra red jelly for the very top layer

In three separate square containers, dissolve each packet of flavored jelly crystals (Apple, Watermelon, and Strawberry) with 1 cup (250ml) of boiling water each. Using less water than the box instructions ensures the jelly is firm enough to handle.
Refrigerate for at least 4 hours or overnight until very firm.
Once set, cut the jellies into small, uneven cubes. Mix them gently in a bowl and keep them chilled until needed.

In a medium bowl, sprinkle the unflavored gelatin over ¼ cup of cold water. Let it bloom for 5 minutes.
Add 1 cup of boiling water to the gelatin and stir until completely dissolved.
Stir in the entire can of sweetened condensed milk until smooth.
Crucial Step: Let this mixture cool to room temperature. If it is too hot, it will melt your colored jelly cubes.

Line a loaf tin with plastic wrap, leaving plenty of overhang on the sides for easy removal.
If you want the red top shown in the photo, pour a thin layer of liquid red jelly into the bottom of the tin first and let it set.
Place the chilled colored jelly cubes into the loaf tin, distributing the colors evenly.
Pour the cooled white cream mixture over the cubes. Tap the tin gently on the counter to remove air bubbles.
The Base: Arrange a single layer of biscuits over the top of the cream mixture. These will become the bottom crust once the cake is flipped.

Fold the plastic wrap over the biscuits and refrigerate for at least 6 hours (ideally overnight).
To serve, peel back the wrap, place a platter over the tin, and flip. Gently lift the tin and remove the plastic wrap to reveal the “terrazzo” effect.
