Elaborate artistic gelatin with intricate floral designs is a masterpiece of Mexican dessert art. This stunning family creation is a showstopping centerpiece for celebrations and special occasions.
Bloom the unflavored gelatin: In a bowl, sprinkle powdered gelatin over cold water and let sit 5–10 minutes until spongy.
In a saucepan over low heat, combine the sweetened condensed milk, evaporated milk, and whole milk. Stir constantly and slowly heat, without boiling, until well mixed and just warm to the touch.
Stir in the bloomed gelatin into the warm milk mixture. Continue stirring over low heat until gelatin is fully dissolved and the mixture is smooth; do not let it boil.
Remove from heat. Stir in sugar and vanilla extract. Divide mixture: pour white base into a large gelatin mold (reserving 1 cup for colored floral details). Chill mold until slightly set but not firm, about 20–30 minutes.
Meanwhile, color reserved gelatin portions with assorted food coloring. Using specialized gelatin tools or syringes, inject colored gelatin into the semi-set base to create intricate floral designs. Chill the entire mold for at least 1 hour or until completely firm before unmolding and serving.
