- Cold Water: This helps cool down the gelatin mixture before layering; cold water is essential for proper setting.

Mix the First Layer: In a bowl, dissolve one packet of flavored gelatin in one cup of boiling water until fully dissolved. This should take about 2-3 minutes.
Add Cold Water: Stir in half a cup of cold water to cool down your mixture slightly. It should feel warm but not hot to touch.
Layering Time!: Pour the first layer into an 8×8 inch glass dish and place it in the refrigerator until firm—this usually takes about 30 minutes.
Create Creamy Layers: While waiting, mix another packet of gelatin with one cup boiling water and add half a cup of cold water along with half a cup of sweetened condensed milk. Mix thoroughly until smooth.
Add the Second Layer: Once the first layer has set completely, pour this creamy mixture over it gently to avoid disturbing the layer below. Return to the fridge until firm again.
Repeat and Build Up Colors!: Continue this process by alternating between flavored layers and creamy layers until your dish is filled or you run out of ingredients—whichever happens first! Each layer should firm up before adding the next one (30 minutes each). hearty main dish
