Following up on this post, I'm revisiting the 4:1:1 daiquiri - in this case 2 ounces of white rum (Denizen), 0.5 ounces of fresh lime juice, and 0.5 ounces of simple syrup. I might be coming around to this line of thinking, as the rum is more clearly highlighted than with my usual 4:2:1. Depending on the quality of the rum base, 4:1:1 may be the way to go. I'll probably have to run some more experiments to be sure...
