Recipe as displayed on the wall at Cabo Wabo Cantina, Sammy Hagar's restaurant/bar in Cabo San Lucas, Mexico. VERY potent! Can be served straight up as a martini, on the rocks, or blended as a frozen margarita. FYI: Damiana Liqueur is a light herbal-based liqueur from Mexico. It's made with the damiana herb that grows in Baha California, Mexico. The bottle is uniquely shaped and is modeled after an Incan Goddess.
