The next time a recipe calls for the juice of a lemon, get the most from your lemon by following the tips below: 1.The best lemons for juicing are those with thin skins. 2.Bring your lemon to room temperature before juicing. 3.Roll the uncut lemon under the palm of your hand, pressing down hard at the same time. This breaks up the membranes inside the lemon which releases more of the juice. 4.Slice the lemon in half and harvest the juice.
