Mexican Mosaic Jello is a fun, colorful, and pretty multi-colored gelatin dessert that resembles a cathedral window. Cubes of different colored jello are mixed in with a white tres leches (3-milk) gelatin, which makes the white background for the dessert.
Pour the jello into small square containers and refrigerate until well set at least an hour.
Cut the jello into ½ inch cubes.
Pour the remaining half cup room temperature water into a bowl and sprinkle with the four envelopes of unflavored gelatin. Let it sit for 5 minutes, then microwave for 30 seconds and stir until there are no clumps. Continue to heat for another 15 to 20 seconds until totally melted.
1 box Unflavored gelatin
Combine the milks and vanilla and pour the gelatin into the milk and stir.
Pour a little of the milk mixture into your mold or 9x13 inch pan. Spread out the jello, then pour the remaining milk mixture over the jello.
Refrigerate for up to 4 hours.
Notes
Tips:
Make sure you bloom the gelatin. Pour the unflavored gelatin over the water and let it sit for 5 minutes. Then heat in the microwave till melted. Don’t worry if your containers are not all the same. You will be cutting the jello into small ½ inch cubes.
Don’t cut the jello into smaller cubes. They won’t show the beautiful mosaic appearance if they are too small.
To unmold the jello, dip the bottom of the mold in warm water. This will loosen the jello; then, you can flip it upside down on a serving platter
Storage. Store in an airtight container in the refrigerator for up to 5 days.
