|Grapefruit soda (we love Jarrito, San Pellegrino and Ting)||150||5|
|Salt or Tajin seasoning|
Wet the rim of a large highball glass with lime and dip the rim in crystal/flaky sea salt or Tajin.
Add Livener and fill the glass to the rim with ice cubes. Top up halfway with grapefruit soda, stir and add more ice before filling the glass the rest of the way with more grapefruit soda.
Garnish with grapefruit wheel.
