Okay, lets talk pronunciation: its kai-pur-een-ya. There you go, now you too can sound worldy like us. Cachaa is another tough one its pronounced ka-sha-sa. You could substitute regular rum for cachaa, but we dont recommend it; this drink is inexorably linked to the grassy, fruity, musty flavors of real sugarcane cachaa. The amount of sugar and lime called for is a hot topic of debate among connoisseurs, as is the type of sugar (granulated, syrup, or cubes). Start with a teaspoon of sugar, or two teaspoons of syrup, or a single cube, and increase to taste. If your limes are small, out-of-season, or just not all that sweet and juicy, feel free to use a whole lime instead of just half.
