3 boxes flavored jelly (Jell-O) – different colors (3 oz / 85 g each)

1 box unflavored gelatin (plain, 7 g / ¼ oz)
-
1 can sweetened condensed milk (14 oz / 395 g)

STEP-BY-STEP INSTRUCTIONS
Step 1: Make the Colored Jellies
-
Prepare each flavored jelly separately.
-
For each box:
-
Dissolve jelly powder in 1 cup hot water (use HALF the usual water).
-
Stir until completely dissolved.
-
-
Pour each color into shallow containers.
-
Refrigerate 2–3 hours, until fully firm.
👉 Less water = firmer cubes that hold shape.
Step 2: Cut into Cubes
-
Once set, cut each jelly into ½-inch cubes.
-
Gently mix all the colors together.
-
Spread cubes evenly in a lightly greased 9×9-inch dish or mold.

-
In a bowl, dissolve unflavored gelatin in 1 cup hot water.
-
Stir until completely clear.
-
Add sweetened condensed milk.
-
Mix well and let cool 5–10 minutes (lukewarm, not hot).
⚠️ If too hot, it can melt the cubes.
Step 4: Assemble
-
Slowly pour the milk mixture over the jelly cubes.
-
Tap dish gently to remove air bubbles.
-
Make sure cubes are fully covered.
Step 5: Chill & Set
-
