Cocktail of tequila, lemon or lime juice, and an orange-flavoured liqueur (9)
I believe the answer is:
margarita
(Other definitions for margarita that I've seen before include "Tequila/citrus cocktail" , "Spanish girl" , "Cocktail consisting of tequila and lemon juice" , "Caribbean island" , "Tequila and lime cocktail" .)
