Peel and chop cucumber into small pieces, then blend with approximately 4 cups of water until smooth.

Strain the blended cucumber mixture into a large pitcher using a fine mesh strainer.

Add fresh lime juice and desired sweetener to the cucumber liquid, mixing well.

Stir in chia seeds, mix, and let sit for 10-15 minutes to allow seeds to swell.

Give a final stir, garnish with lime slices and cucumber ribbons, and serve immediately.

Store in a sealed container for up to 2-3 days, stirring before serving.
