Lemon juice

Jif is a brand of lemon juice sold in the United Kingdom and Ireland, by Reckitt & Colman. Notable for its unique plastic lemon containers usually known as "jiffy lemons" or "jif lemons", it is also sold in bottles. A well-known advertising campaign introduced the catch-phrase "Jif lemon day (don't forget the pancakes)", due to the popularity of lemon juice (and specifically Jif) with pancakes on Shrove Tuesday.
