Fill a highball glass generously with ice cubes.
Pour 60ml of gin over the ice.
Add 80ml of freshly squeezed lemon juice.
Gently stir once or twice to combine without over-diluting.
Express a lemon peel over the glass to release its oils, then place it on the rim as garnish.
Serve immediately.
80ml of lemon juice is exceptionally high for a two-ingredient build - consider whether the recipe intends a longer, more diluted serve or if a small measure of simple syrup would balance the acidity without compromising the minimalist ethos.
