Create convincing rubbery "watermelon" snacks without the fruit using this simple gelatin-based recipe. Ideal for sensory play or food-safe props.
Ingredients & Equipment
- 1 cup Water (boiling)
- 1 cup Water (cold)
- 6 oz (3 packets) Watermelon or Berry Flavored Gelatin Powder
- 1 oz (1 packet) Unflavored Gelatin Powder
- Mini Semi-Sweet Chocolate Chips
- Green Liquid Food Coloring (optional)
- Silicone Rectangular Loaf Pan (or small dish)
- Small Round Cutter or Lid (about 1.5 inch diameter)
- Cooking Spray
Instructions
1. Prepare Gelatin: Dissolve the unflavored gelatin powder in 1 cup of cold water in a medium bowl. Let it soften for 5 minutes.
2. Combine Liquids: Pour 1 cup of boiling water over the bloomed unflavored gelatin mixture. Stir constantly until completely dissolved.
3. Add Flavor & Color: Whisk in the watermelon/berry flavored gelatin powder. Stir until fully dissolved and no granules remain.
4. Create Rind (Optional): Ladle out approximately ½ cup of the clear gelatin mixture into a small bowl. Tint it light green with food coloring. Set aside.
5. Layer White: Lightly spray your silicone loaf pan with cooking spray. Carefully pour the clear, uncolored watermelon gelatin mixture into the pan. Chill until just set but still slightly sticky (about 45-60 minutes).
6. Add Seeds: Once the clear layer is set, gently press mini chocolate chips into the surface, spaced randomly like seeds.
7. Finish Setting: Carefully pour the green tinted gelatin mixture (if using) over the clear layer with seeds. Refrigerate everything for 4-6 hours, or overnight, until completely firm.
8. Cut Watermelon Wedges: Loosen the gelatin block from the pan. Cut it lengthwise into long strips about 1-inch wide. Cut these strips on a diagonal every 1.5 inches to create wedge shapes.
Tips
- Adding unflavored gelatin significantly boosts the rubbery, gummy texture.
- Ensure layers fully set before adding next to prevent mixing.
- Store tightly covered in the refrigerator for up to 1 week.
- For non-edible props (e.g., science projects), omit chocolate chips.
