Once the gelatin has bloomed, gently heat it in the microwave for about 10–15 seconds, or until it is just warm enough to dissolve completely. Stir the gelatin mixture until it is clear and smooth, with no visible lumps. Avoid overheating, as this can weaken the setting power of the gelatin.
Add the warm gelatin mixture to the apple juice and caramel mixture. Stir well and slowly to ensure everything is combined thoroughly. The mixture should appear glossy and evenly blended, with a slightly thicker consistency than plain liquid.
Pour in the vodka and mix again until the ingredients are well blended. Stir gently but thoroughly to avoid creating too many air bubbles, which can affect the clarity and texture of the lollipops once they are set.
Carefully pour the mixture into the prepared silicone lollipop molds, filling each mold close to the top. Leave a small amount of space at the top to prevent overflow when inserting the sticks. Work slowly and steadily to keep the fills even and neat.
Insert a lollipop stick into each mold, ensuring it stands upright and is centered in the mixture. Adjust the stick position gently if needed so it remains straight and well-placed while the lollipops set.
Place the filled molds in the refrigerator and allow them to chill for at least 4 hours, or until the lollipops are completely set. During this time, the mixture will gradually firm up to a soft but stable texture that holds its shape when removed.
Once the lollipops are firm, carefully remove them from the molds. If they are sticking, gently flex the silicone mold to help release them without breaking the shape.
Serve the Caramel Apple Vodka Lollipops immediately, or store them in an airtight container in the refrigerator until you are ready to enjoy them. Keeping them chilled helps maintain their texture and freshness.
