Hold the zester at approximately a 45-degree angle against the fruit. This allows you to remove just the zest without digging into the bitter white pith.
The key to successful zesting is removing only the outermost layer of the fruit's peel, which contains the flavorful oils. The white layer beneath, called the pith, is bitter and undesirable. Holding the zester at a 45-degree angle helps you achieve this precision. Here's a step-by-step breakdown:
Prepare the Fruit: Wash and dry the fruit thoroughly. This removes any dirt or residue.
Position the Zester: Hold the zester in one hand and the fruit in the other. Position the zester at a 45-degree angle against the fruit's surface.
Apply Gentle Pressure: Apply gentle, even pressure as you draw the zester across the fruit. Avoid pressing too hard, which can dig into the pith.
Rotate the Fruit: Rotate the fruit as you zest, ensuring you only remove the colored part of the peel. Avoid zesting the same area twice, as this can also lead to pith removal.
Inspect the Zest: Check the zest for any white pith. If you see any, discard it.
Use a microplane zester for the finest zest. For larger zest strips, use a channel knife or vegetable peeler, then carefully trim away any attached pith with a paring knife.
