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

Units Scale
  • 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

  1. 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.
  2. Pour each cooled gelatin mixture into separate shallow pans (like 8×8″), and chill until firm but still pliable, about 30–45 minutes.
  3. Remove jiggly gelatin and cut into irregular “sea glass” shapes using a sharp knife.
  4. Divide shapes by color in a large clear bowl or individual cups.
  5. Prepare cloudy binder: whisk condensed milk with 1 cup boiling water until smooth, then stir in 1 cup cold water and cool slightly.
  6. Gently pour binder over sea glass pieces just to cover. Chill until set, about 2 hours.
  7. 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.
