Been flirting with cucumber and basil.  This is a riff on a Collins. 1 1/2 oz gin (Tanqueray 10)1/2 oz cucumber simple syrup**3/4 oz lemon juice1/2 oz cucumber juice*4 oz soda water2-4 basil leavesIn a shaker tin, muddle 2-3 basil leaves with cucumber syrup and lemon juice.  Add cucumber syrup and give a quick shake with a few pieces of cracked ice.  Strain into collins glass with over fresh cracked ice.  Top with soda water and garnish with a bruised basil leaf, wiping the rim of the glass with the oils. *I juiced 2 cucumbers using a centrifugal juicer but you could also use a high-powered blender and strain.**Use cucumber juice to make a 1:1 syrup in your preferred method. I tried just infusing fresh cucumber slices into a syrup but it doesn't impart enough flavor. I found it to be quite refreshing.  The cucumber juice in addition to the cucumber syrup was needed to really punch up the cucumber flavor.  The Tanqueray 10 had the right notes of citrus to play well with the cucumber and basil.
