FAQs
Can I use sugar-free gelatin?
Yes, sugar-free gelatin works well and reduces overall sugar content.
Is this recipe gluten-free?
Yes, as long as the gelatin used is labeled gluten-free.
Can I make this dessert ahead of time?
Absolutely. It’s best when made a day in advance to allow it to fully set.
What kind of pan should I use?
A 9×13-inch glass or metal pan works best for even setting and easy cutting.
Can I use more than three colors?
Yes, feel free to use as many as you like for a more colorful effect.
Why does the milk mixture need to cool?
Pouring it hot can melt the colored gelatin cubes and blur the design.

No, sweetened condensed milk is needed for the creamy texture and sweetness.
Can I use juice instead of water?
Yes, but this may slightly alter the texture and taste.
Can I add flavorings to the milk base?

Description
A shimmering, colorful Sea Glass Jello that resembles polished sea glass—vibrant, translucent, and perfect for a refreshing dessert platter.
Ingredients
- 3 small boxes (3 oz each) clear-flavored gelatin (lime, lemon, white grape)
- 3 cups boiling water, divided
- 3 cups cold water, divided
- 1 can (14 oz) sweetened condensed milk
- Ice cubes and cold water (to gently cool layers)
Instructions
- Prepare colored layers: for each flavor, dissolve 1 box in 1 cup boiling water, stir until clear. Add 1 cup cold water and a few ice cubes to cool quickly without setting.
- Pour each cooled gelatin mixture into separate shallow pans (like 8×8″), and chill until firm but still pliable, about 30–45 minutes.
- Remove jiggly gelatin and cut into irregular “sea glass” shapes using a sharp knife.
- Divide shapes by color in a large clear bowl or individual cups.
- Prepare cloudy binder: whisk condensed milk with 1 cup boiling water until smooth, then stir in 1 cup cold water and cool slightly.
- Gently pour binder over sea glass pieces just to cover. Chill until set, about 2 hours.
- Serve chilled—sea glass pieces should float in milky-clear gelatin for a stained-glass effect.
Notes
- Work in a cool area to slow gelatin setting while cutting shapes.
- Use irregular cuts for authentic sea glass appearance.
- If pieces float unevenly, gently press them down before binder firms.
- Store in fridge up to 3 days; serve within a few hours of slicing for best look.
- Try pastel colors like peach, blue raspberry, or cranberry for variation.
