Gently muddle one orange slice, one cucumber slice, and one lemon slice in a cocktail glass.
Fill glass with ice.
Pour in gin and top with ginger ale.
Stir, then garnish with additional orange and cucumber slices, and a sprig of mint.
This drink is called a "Pimm's Cup" because it traditionally uses Pimm's No. 1 gin. Feel free to substitute with your favorite gin, as I have. This drink does not need too much fruit, as it's refreshing just as it is!
