Orange or Grape Blocks

Pour orange juice or grape juice into a small saucepan and add the water, stirring to combine.

Sprinkle the unflavored gelatin over the juice mixture and let sit for 2 minutes to bloom.

Heat the saucepan over medium heat, stirring constantly until the gelatin dissolves completely, about 3-5 minutes.

Remove from heat and stir in the vanilla extract until well combined.

Pour the mixture into an 8x8-inch baking dish or similar shallow pan and refrigerate until completely set, about 3-4 hours.

Once set, cut the gelatin into small cubes or blocks using a sharp knife, dipping the blade in warm water between cuts for clean edges.

Serve the blocks chilled as a light dessert or snack.
