That's why granitas happen to be one of my favorite entertaining tricks. First of all, no cocktail looks prettier than when it's been frozen into thousands of gorgeous ice crystals piled into a glass like so many gems. Second -- and not to get all technical here -- but one of the most tricky aspects of cocktail making is dilution, or the amount of melted ice water that makes it into your final drink. When your drink and tastes too weak or too strong, dilution is often to blame. It can also mess with the temperature of the drink, which will throw the sweet-acid balance off as well (we taste sweetness more strongly at warmer temperatures -- go figure). So basically, dilution is often the culprit in a bad drink. In this granita, dilution is completely controlled, so it tastes the same -- amazing -- every time.
