Lemonade is a lemon-flavored soft drink.
The term can refer to two different types of beverage:
In the U.S., Canada, Brazil, Cuba, Romania and Italy, lemonade refers to an uncarbonated mixture of lemon juice, sugar, and water. In India and Pakistan, where it is commonly known as limu paani or nimbu paani, lemonade may also contain salt. In Brazil, lemonade is, sometimes, made with full lemons (including the skin) instead of just lemon juice.
In Germany, the UK, Australia, and New Zealand the term mainly refers to a colourless, carbonated, sweet soft drink containing either natural or artificial lemon flavor, such as Schweppes Lemonade. 7 Up and Sprite are similar but are lemon-lime flavoured and so arguably not lemonade.
