Keep the sweetness of your ingredients in mind when making this. If your sake is on the sweet side or you made the mistake of buying sweetened coconut water you might want to forgo the sugar syrup entirely, but in my case (dry sake, water straight from the nut and a spirit that’s only vaguely sweet) I cut the syrup in half. The sweetness does round out the flavors in this delicate and delightful drink. In keeping with the theme I gave it a twist of yuzu, works great!
