Shine that lime
“The first secret of a perfect caipirinha is a shining lime,” says Kennedy Nascimento, bartender of Riviera Bar in São Paulo. The quality of the lime is just as important as the quality of the spirit, he says. “Slice both edges off and then cut in half, not across the width, but from one end to the other, then remove the center and cut into eight cubes. Put the pieces in a glass, sliced side face up, and top with sugar.” Nascimento prefers organic demerara sugar.
