Tequila blanco offers a clean flavor, while mezcal adds smokiness. Rum can be substituted for a tropical twist. Adjust jalapeño for preferred spice level. For a mocktail, skip the tequila and add extra sparkling water or pineapple juice. To make a pitcher, mix all except sparkling water in advance, then add bubbles before serving for best fizz. Use fresh lime juice and cold sparkling water for best taste.
