How to Make Easy Edible Aquarium Terrariums – The Best Ocean-Themed Gelatin Dessert
- In a small bowl, sprinkle the unflavored gelatin over 2 cups of cold water to bloom for 5 minutes.
- Warm 2 cups of water in a saucepan over low heat, then add the bloomed gelatin and sugar (if using), stirring until completely dissolved. Let cool slightly.
- Pour the dissolved unflavored gelatin into clear glass or plastic cups to create the “water” base. Chill in the fridge for about 1 hour until slightly firm but still sticky.
- Prepare the blue raspberry gelatin according to package instructions using 1 cup cold water; allow it to cool but not set.
- Layer blue gelatin over the unflavored gelatin in the cups gently. Insert candy fish gummies and green gummy worms by pushing them sideways into the gelatin to create an underwater scene. Chill for at least 2 hours until fully set.
- Before serving, decorate the top with mini marshmallows to mimic coral or bubbles and garnish with fresh mint leaves for a pop of color and freshness.
Tips for the Best Results
- Use clear cups or jars to showcase the beautiful layers and candy decorations clearly.
- Allow the unflavored gelatin base to partially set before adding candy to keep them suspended.
- Choose candies that won’t bleed color to keep the “water” looking clean and vibrant.
- For an extra ocean vibe, add a sprinkle of edible glitter or blue sugar crystals on top.
- Serve chilled and keep refrigerated until ready to enjoy for the freshest texture.
Storage and Reheating
Store your ocean-themed gelatin dessert in the refrigerator covered with plastic wrap or lids to keep moisture in and protect from odors. They are best enjoyed within 3 days for optimal texture and flavor.
Since this is a gelatin-based no-cook dessert, reheating is not recommended. Keep chilled and serve cold for the best experience.
