For cooks who like the punch that citrus adds to food, there is Flexi Zesti ($9.95), a tool that removes the flavorful colored part of the rind but leaves behind the bitter white pith. From Microplane, known for its ultra-sharp zesters and graters, Flexi Zesti is small enough to fit in the palm of your hand. It has two pieces: a blade fitted into a removable silicone cover and a curvy bottom piece to collect the zest. As the zester glides over the fruit, the blades remove the outer rind, which falls into the collecting chamber underneath. Then, it’s just a matter of removing the cover and scraping out the zest.
