Prepare a tall glass full of ice then add the Pimm's No. 1 (an English-invented gin-based drink with citrus and other flavors infused), to 1/3 full.

Fill the remaining 2/3 of the glass with lemon-lime soda (I prefer Slice, but do what you will).

It is traditional to garnish with a wedge of cucumber.

Extra tasty with an (optional) bit of crushed mint.

Delicious and refreshing!
