A hybrid.

2oz tequila

2oz fresh grapefruit juice

1 oz fresh lime juice

1/2 oz Campari

1/2 oz simple syrup

Shake all, add 2 oz fizzy water, dirty pour into glass.

Delicious, honestly. Increase the sugar if you want it more Paloma like, or more of the Topo Chico, to make one like like Texas ranch water. Sub mezcal if you really hate Campari, but you may like it in this.
