General Comments: Making sugar syrup is almost as much of a pain as juicing limes. It's a good job that this is so clearly worth it, then. It's a bit plain looking, but if you're going to go with something plain, green is definitely the best choice. And it tastes absolutely wonderful, sweet and sour and, er, a third thing, that comes from the rum. Rummy, I guess.
Also, daiquiri is a great name. It's so commonly used that it might seem a bit boring, but just try saying it. "Daiquiri." Really put your back into it. "DAIQUIRI".
