Gather your ingredients: large English cucumbers, freshly squeezed lime juice, granulated sugar, fresh mint leaves, fresh ginger, and water.

In your blender, combine the chopped cucumbers, lime juice, sugar, most of the mint leaves, ginger, and 2 cups of water. Blend on high speed until smooth, about 30-45 seconds.

Strain the blended mixture through a fine mesh sieve into a pitcher, pressing down on the pulp to extract as much liquid as possible.

Add the remaining 2 cups of water to the strained mixture in the pitcher. Stir well and adjust sweetness or tartness as needed.

Cover the pitcher and refrigerate the agua fresca for at least 30 minutes to chill.

Serve over ice-filled glasses and garnish with reserved mint leaves.
