How to get the most juice from your fruit
To increase the amount of juice you can get from a lemon (or any other citrus fruit), press and roll the lemon firmly on a work top for a minute or so before squeezing. This will cause the pockets of juice in the fruit to pop open so that when you cut the fruit open and squeeze it, you will find it easier to get the juice out. Alternatively, try putting the fruit in the microwave for a few seconds before squeezing.
