Squeeze some lemons to make lemon juice. You will need 2 cups (450 milliliters) of lemon juice, which will take about eight to ten lemons. Cut the lemons in half, and use a citrus squeezer, a hand juicer, or a wooden reamer to squeeze the juice from the lemons.
To get more juice out of each lemon, roll the lemons across a flat surface while pressing down on them. Do this before cutting and juicing them. The rolling and pressing motion loosens the flesh inside and helps the lemons release more juice when you squeeze them.
