[edit] Uses
Lemon juice is used to make lemonade, and is (along with lime juice) an important part of many cocktails. It is also used to make cream cheese and is effective in curdling milk.[1] It is high in vitamin C, which led Gilbert Blane to use it to fight scurvy in the British Navy.[2]
Lemon juice has a pH of around 2.3 [3] and is good for removing the tarnish from pennies that are made from mainly zinc. It can also be used in writing secret messages that can be revealed by fire.[4]
