Simple Syrup Preparation – In a small saucepan, combine sugar and filtered water.Bring to a gentle simmer over medium heat, stirring until the granules fully dissolve (about 5 minutes). Remove from heat and let the syrup cool in the fridge for roughly 30 minutes—this step ensures the syrup is crystal clear.
Cucumber Juice Extraction – While the syrup chills, pulse the chopped cucumber in a food processor until it forms a coarse pulp (about 1–2 minutes). Transfer the pulp to a fine mesh strainer set over a bowl; let it drip for 10–15 minutes to yield around ½ cup of fresh cucumber juice. Press gently with a spatula to extract every drop—this concentrates flavor and aroma.
Final Assembly Chill – In a large pitcher, stir together the cooled syrup, strained cucumber juice, and lemon juice until fully blended. Taste and adjust sweetness or acidity, adding a splash of sparkling water if you prefer a lighter fizz. Chill for at least 15 minutes before serving, then pour over ice and garnish with cucumber and lemon slices.
