The lemon is used for culinary and nonculinary purposes throughout the world – primarily for its juice, though the pulp and rind (zest) are also used, mainly in cooking and baking. Lemon juice is about 5% to 6% citric acid, which gives lemons a sour taste, and a pH of 2–3. Many lemon-flavored drinks and candies are available, including lemonade and sherbet lemons. The distinctive sour taste of lemon juice makes it a key ingredient in many dishes across the world.
