3-Ingredient Jello Gummy Hearts (How to Avoid Bubbles)

5 from 1 vote
These homemade gummy hearts use just three ingredients and simple food science to create a treat that is firm, chewy, and crystal clear. The secret lies in the "dry whisk" method and controlling your agitation to prevent cloudiness.
The Science: The "Bloom" Ratio: Standard Jell-O uses 2 cups of water for one box, which creates a soft, wobbly gel. By adding two extra packets of unflavored gelatin (pure collagen protein) to a decreased volume of liquid, we increase the protein network density. This creates a "gummy" texture that is firm enough to hold its shape at room temperature without melting.
The "Anti-Bubble" Technique: Most people whisk gelatin vigorously, which whips air into the mixture and creates a cloudy, foamy layer on top. By whisking slowly and dry-mixing the powders first, we ensure a glass-like, transparent finish that looks like a gemstone. Cooking it while mixing also helps to increase the rate at which the gelatin granules dissolve.

Ingredients
  

  • 2 Box 6 oz Strawberry Gelatin Jell-O brand
  • 2 Packets Unflavored Gelatin Knox brand
  • 2 cups Water

Equipment

Method
 

  1. The Dry Mix: In a medium mixing bowl, combine both boxes of flavored Jello and both packets of unflavored gelatin. Whisk them together dry. This ensures the high volume of unflavored gelatin powder doesn't "clump" when it hits the boiling water.
  2. Boil and Dissolve: Bring 2 cups of water to a boil in a saucepan. Pour in your dry powder mix. Reduce heat to medium-low. Stir constantly but gently for 3–4 minutes. Lower the heat as needed to prevent boiling over.
  3. The Pour: Carefully pour the gelatinous liquid into your silicone molds. 
  4. The Set: Chill in the refrigerator for at least 4 hours.

Notes

The "Super-Set" Secret: Using two 6oz boxes of Jello creates a significantly higher sugar-to-water ratio. This makes the gummies more shelf-stable and gives them a "snap" when you bite into them. Also, setting your silicone molds on a sheet tray helps to make sure the gelatin mixture doesn't spill over when being transported to the fridge.
