Out here in Nuevo Mexico I wanted to celebrate Mexican Independence Day by make margaritas with Mexican limons, which are hard to find Stateside, and remembered my take on Difford's Yuzu Margarita, which probably comes close. Difford had the stunningly good idea (why didn't I think of it?!) of making margaritas with Cointreau replaced by Ferrand Limited Edition Late Harvest Yuzu Curacao but replaced the lime with yuzushu liqueur, whereas I just use yuzu juice (see his page on Yuzu Margaritas).
