Guava is my first choice here, but you can substitute passion fruit or mango purée if you’d like. I like tequila reposado because its aged in oak which gives it a smooth, caramel-like flavor that I especially enjoy with fruit. You can use blanco or silver tequila for a brighter drink, or añejo for something richer and more oak-forward. Mezcal also works well if you prefer a smokier, more mineral flavor.
