Cut the lemon lengthwise to extract the maximum juice.
There are different ways you can juice a lemon. You can use a lemon squeezer or a hand-held juice press to juice the lemon. Otherwise, you can juice the lemon the old-fashioned way with a fork. Make sure you do this over a strainer to catch the bitter lemon seeds.
Add a cup of water and mix well. Your lemon juice is ready!
If you want to sweeten your lemon juice, you can add sugar or honey as per taste. Adding a pinch of salt to the juice helps to heighten the sour flavor of the fresh juice.
Notes
If you want to extract the maximum juice from a lemon, you can choose a heavy lemon and slightly roll it under your palm on a counter to loosen the fruit. You can also stick it in a microwave for 20 seconds just before juicing it to make it softer.
