Pour your chilled mix over some fresh ice in a tumbler. Add plain or grapefruit soda if you like. Pop on a garnish and send it out right away.

Drop 3–4 ice cubes in. Close the shaker and shake it up for about 15–20 seconds so everything's super cold.

In a jar or cocktail shaker, pour in the grapefruit juice, lime juice, sweetener, apple cider vinegar, and a bit of sea salt.

Spread some salt or Tajin on a plate. Rub a wedge of lime or grapefruit along your glass's edge, then dip and twist it in the salt or Tajin so it sticks just a little.
