Made a couple of Daquiri's last night. Both of them made with 2 oz Mt Gay rum and 1 oz of fresh lime juice. Used 1/2 oz simple syrup on first(as recipe calls for) and 1 oz simple syrup on second.
Maybe my limes are strong or my simple syrup is weak, but I went to 1 oz of the syrup as the 1/2 oz didn't balance out the tartness of the lime. Second was more balanced than the first. I liked the daquiri's but I might consider increasing the rum content a bit more.
