Make the cucumber simple syrup:

1. In a saucepan, combine the cucumber chunks, granulated sugar, and water over medium heat.
2. Stir until the sugar has completely dissolved and the cucumber begins to soften. While stirring, I like to break up some of the cucumber bits with the back of my spoon to encourage more flavor mingling.
3. Take off the heat and allow it to cool for about 15 minutes before straining into a container. Store in the refrigerator until ready to use.

Make the honeydew vodka:

1. In a blender, add the vodka and honeydew pieces. Blend until no large chunks remain.
2. Give the mixture a taste. If you aren’t getting much honeydew flavor, add the 1oz of simple syrup and blend again until combined.
3. Strain through a mesh strainer into a sealable container and store in the refrigerator until ready to use.

Make the cocktail:

1. Add the mint leaves, lemon juice, and cucumber simple syrup to a shaker. I like a more acidic cocktail, so I only use .5oz of syrup, but if you like a sweeter cocktail, use .75oz. Muddle until the mint leaves are broken up and have released their oils.
2. Add ice, honeydew vodka, and elderflower liquor. Shake until cold and strain into a highball glass full of ice.
