This 1930s Prohibition-era cocktail from Mexico balances tequila's vegetal bite against sweet-tart grenadine and fresh lime, while Angostura bitters add warm spice notes of clove and cinnamon. The soda water stretches the drink into a long, refreshing sipper that drinks lighter than its bold name suggests. It's essentially a dressed-up tequila highball with genuine complexity—the pomegranate sweetness of real grenadine tempering the agave spirit without masking it.
