What is Mosaic Jello (Gelatina de Mosaico)?

Mosaic jello is made by cutting different flavors and different colors of jello into cubes and immersing these cubes in condensed milk, fruit juice, or tequila!

Traditional mosaic jello is popular in Mexico. It is made by adding lime and strawberry gelatin cubes in a blended mixture of sweetened condensed milk, evaporated milk, and unflavored gelatin*. The color combination reflects the Mexican flag.

This classic Mexican dessert is usually made in a bundt pan* but I made it in a loaf pan instead.

How to make the best Mosaic Jello

Prepare flavored jello

I used fruit gelatins – strawberry, lemon, blueberry, and lime jello but you can use any flavors you like.

As per directions on the box of jello, add 1/2 cup boiling water to one of the flavored gelatin. Mix well and let this cool to room temperature. Then add 1/2 cup yogurt into the mix and stir till combined.

Make sure that the yogurt and the gelatin mix are at room temperature before doing this step. If you find lumps of yogurt floating around, you can filter the solution through the finest sieve you can find.

Set and cut the jello into colored cubes 

Pour the mix into a container and refrigerate overnight. Set the jellos in separate small shallow food storage containers. Repeat the above steps for different jello colors.

After refrigerating overnight, the mix should be set. Run each container under warm water for about 10 to 20 seconds. This helps remove the gelatin easily from each container.

Cut the flavored jellos into small cubes. Add it to your mold and set it aside.

Make Margherita

In a large bowl*, add 1/2 cup of cold water and whisk in the unflavored gelatin. Let it sit for 5 minutes. To this pour in 1 cup boiling water, stirring constantly.

Then add lemon squeeze, margarita mix, tequila, and 1/2 cup cold water. Stir again till combined.

Preparing mosaic jello

Pour the unflavored gelatin mixture over the jello cubes that were set aside. Refrigerate for 6 hours or overnight.

Once it is set, run the mold under warm water for 10 to 20 seconds to help release the jello. Run a thin knife along the sides to further help the release. Invert the mold over a flat surface and the jello should release easily.

Jello can take several hours to set depending on the jello brand and the size of the container used. Place the jello in the refrigerator covered for a minimum of 4 hours or preferably overnight.

Do you have any tips to take it out of the mold easier?

To make sure the jello comes out of the mold easily, dip the knife in warm water and thenrun it around the edges of gelatin to loosen it before removing it from the mold. If the jello still has trouble coming out of the pan, place the mold in hot water for about a minute and try un-molding. Make sure not to let any water get into the jello.
