Using a vegetable peeler, slice thin ribbons of cucumber and place in a cocktail glass. From the remaining cucumber, cut off 3 chunks to muddle into the cocktail. Squeeze the lime juice into a cocktail shaker and add the gin, St Germain, basil, and cucumber chunks. Muddle the ingredients well, and then add ice.
Shake well, then pour into your glass. Top with tonic and garnish with basil.
