In a blender, combine 1 cup of coconut milk, ¼ cup of fresh lemon juice, and ¼ cup of lavender syrup. Blend on high for about 30 seconds until smooth.

Add in 2 tablespoons of honey or agave nectar. Blend again for another 15 seconds to incorporate the sweetener, adjusting sweetness as needed.

Pour in 1 cup of cold water gradually while blending on low speed until the mocktail reaches desired consistency.

Strain the blended mixture through a fine-mesh strainer into a bowl to remove pulp and achieve a smooth texture.

Fill serving glasses with ice cubes. Pour the strained mocktail over the ice, filling each glass about three-quarters full.

Add a slice of lemon and a sprig of lavender to each glass to enhance presentation and aroma.
