The Mix

4oz lime juice (squeezed fresh, like 3-4 limes)

1oz grapefruit juice (yellow, fresh, and sour)

1oz orange liqueur

Several dashes of orange angostura bitters

Shake

3-4oz tequila blanco

A palm of small cubed ice

2oz of the Mix

Pour over more ice and 4oz lime-infused sparkling water

Margarita Gazeuse does not qualify as a happy hour cocktail… those are well swills only.
