Begin by adding the fresh raspberries and water into a blender. Blend the mixture on high speed until it reaches a smooth consistency.
After blending, take a fine mesh sieve and place it over a bowl. Pour the blended raspberry mixture into the sieve. Use a spatula to press down on the solids, extracting as much juice as possible while leaving the seeds behind.
In a separate mixing bowl, combine the freshly squeezed lemon juice with honey or agave syrup, along with the lemon zest. Stir the mixture well until the sweetener is completely dissolved into the lemon juice.
Gradually pour the strained raspberry juice into the bowl containing the lemon mixture. Stir gently but thoroughly to ensure the two liquids are well combined and harmonized in flavor.
Carefully pour the final mixture into your popsicle molds, filling each cavity about three-quarters full to allow for expansion while freezing.
If your molds come with sticks, insert them according to the manufacturer’s instructions. Alternatively, if using standard molds, place the popsicle sticks gently into the center of each filled cavity. Freeze the molds for a minimum of 6 hours, or until each popsicle is firmly set.
When ready to serve, run warm water over the outside of the molds for about 10-15 seconds to loosen the popsicles. Gently pull them out, taking care not to break them.
Notes
For an eye-catching display, serve the popsicles on a vibrant plate, garnished with fresh mint leaves and whole raspberries.
