Roll lemons on counter to release the juice. Cut in half and squeeze into a bowl. After all lemons are juiced, pour into a measuring cup, you want about a 1/2 cup. Juice more lemons if needed.
Place cucumber, lemon juice, mint leaves and agave in a blender and process until well juiced.
Strain the liquid using a fine mesh strainer, pressing the juice from the solids and reserve the liquid.
Add water to the reserved liquid and taste. Add more lemon or sweetener if desired.
Pour over ice to serve. Garnish with mint leaf, lemon slices and fresh mint.
Tips for BEST results:Choose lemons in the market that have a little give when you squeeze them for maximum juiciness.Use fresh lemon juice. The flavor is worth the effort. Serve up cucumber mint lemonade super cold with lots of ice and maybe even a frozen glass!Don’t forget to strain the solids off after blending. It’s ok if a few get through but you don’t want too much pulp in it.Roll your lemons first on the counter while pressing down firmly with your hand. This step releases more juice from the lemons for more flavor.If you are having a tough time squeezing, use a spoon to release the juice in the lemon half. It's ok if you get a little pulp in there since we will be straining later.
