In Britain and some other countries, lemonade normally means a clear, lemon-flavoured carbonated soft drink, similar to 7-up
without the lime flavour. Can be quite pleasant or fairly nasty depending on the quality of flavourings and sweetener used.
Commercial versions of the cloudy drink Americans call "Lemonade" are sold there as "Traditional Lemonade".
Supposedly the Irish
call this clear drink "white lemonade" because they also have something called "red lemonade" which looks and tastes different.
