Zest lemon, halve, and juice. Use zest only if using a zester or a microplane.Want to get the most juice out of your lemon? Before cutting, we recommend microwave lemon 15-20 seconds to "soften" the fruit. Then, gently roll the softened fruit on your work surface while pressing on it with your palm. Finally, place a cut half in between the arms of a pair of tongs to make squeezing much easier.
