Instructions:

Fill a highball glass with ice cubes.

Pour in the Pimm's No. 1 Cup and the lemonade or tart lemon-lime soda into the glass, stirring gently to combine them together.

Add cucumber slices and/or mint leaves if desired, then stir again to evenly distribute them throughout the drink.

Garnish with an orange slice and a sprig of fresh mint before serving cold!
