Begin by adding 1 cup of coconut milk, 1 cup of freshly squeezed lemon juice, and 1/2 cup of lavender syrup into a blender. Blend on high for about 30 seconds until smooth.

Incorporate 2 tablespoons of honey or agave nectar into the blender and blend again for another 15 seconds until fully integrated.

Gradually pour in 2 cups of cold water into the blender while it runs on low speed. Blend for an additional 15 seconds until well combined.

Use a fine-mesh strainer over a bowl to strain the mixture, eliminating any pulp and ensuring a smooth liquid.

Fill glasses with ice cubes and pour the strained mixture over the ice.

Garnish with lemon slices and lavender sprigs before serving.
