The tree's ellipsoidal yellow fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, which has both culinary and cleaning uses.[2] The pulp and rind are also used in cooking and baking. The juice of the lemon is about 5-6% citric acid,^{[citation needed]} with a pH of around 2.2,[3] giving it a sour taste. The distinctive sour taste of lemon juice, derived from the citric acid, makes it a key ingredient in drinks and foods[4] such as lemonade and lemon meringue pie.
