I made this drink and didn't like it much. I used small key limes but they seem as sour as a regular lime so it's like drinking lime juice and creamo mixed with vodka. Way too sour for me. It improved when I added brown sugar. Are key limes in Florida actually sweet as compared to the ones we import to northern climes? Key Lime Martini Coral Reef Café, Epcot 1 serving 2 oz.
