To maximize zest yield, use a microplane zester, apply even pressure, rotate the fruit as you zest, and avoid the bitter white pith.
Getting the most zest from your citrus fruits involves a combination of technique and the right tools. Here's a breakdown:
Use a Microplane Zester: A microplane zester is the best tool for the job. Its fine blades efficiently remove the zest without digging into the bitter white pith underneath. Other zesters, like those with larger holes, can remove too much pith, reducing the zest's flavor and increasing bitterness.
Apply Even Pressure: When zesting, apply consistent, moderate pressure. Too little pressure won't remove enough zest, while too much will scrape off the pith.
Rotate the Fruit: As you zest, rotate the fruit in your hand, ensuring you zest the entire surface evenly. Avoid zesting the same spot multiple times, as this increases the likelihood of hitting the pith.
Avoid the Pith: The white pith beneath the colored zest is bitter and undesirable. Focus on removing only the colored outer layer. If you accidentally get some pith, try to remove it from the zest before using it.
Zest Before Juicing: It's much easier to zest a firm, whole fruit than a squeezed one. Zest your citrus before juicing to avoid a slippery, awkward situation.
Consider the Fruit's Condition: Fresh, firm citrus fruits yield more zest than older, softer ones. Choose fruits that feel heavy for their size, indicating they are juicy and have a good amount of zest.
If you accidentally zest too deeply and get some pith, you can try soaking the zest in cold water for about 30 minutes. This can help to leach out some of the bitterness. Drain the zest well before using it.
