01 - Combine raspberries and lemon juice in a small saucepan. Heat over medium heat until the berries break down and release their juices, approximately 3 to 4 minutes.
02 - Purée the cooked mixture using an immersion blender or standard blender until completely smooth. For a seedless finish, press the purée through a fine mesh sieve.
03 - Return the purée to the saucepan. Add honey or maple syrup and stir until fully incorporated.
04 - In a separate small bowl, sprinkle the gelatin powder evenly over the cold water. Allow it to rest for 2 minutes to bloom and absorb the liquid.
05 - Gently warm the raspberry purée over low heat. Add the bloomed gelatin and stir constantly until fully dissolved. Do not allow the mixture to boil.
06 - Pour the liquid into silicone gummy molds or a parchment-lined baking dish. Smooth the surface with a spatula if necessary.
07 - Refrigerate for at least 45 minutes, or until the gummies are firm and fully set.
08 - Carefully remove the gummies from the molds. If using a baking dish, cut into bite-sized pieces. Store in an airtight container in the refrigerator for up to 1 week.
