Moroccan citron
The Moroccan citron was described by the Moroccan professor Henri Chapot, as being a sweet citron, meaning that its pulp is low in acid. He discovered that the acidity in the more common citrons or lemons, is represented by red on the inner coat of seeds specifically on the chalazal spot, violet pigmentation on the outer side of the flower blossom, and also by the new buds that are reddish-purplish. The Moroccan citron which is acidless is completely lacking the red color. This designation was cited by Herbert John Webber and Leon Dexter Batchelor the editors of the fundamental treatise on citrus, namely The Citrus Industry, which was published by the University of California, Riverside in 1967.
Saint Clement's (cocktail)
The Saint Clement's is a non-alcoholic cocktail. Though the ingredients may vary, it consists of orange juice mixed with bitter lemon, usually in equal proportions; the name of the drink refers to the English nursery rhyme Oranges and Lemons. The drink is therefore named (indirectly) after either St Clement Eastcheap or St Clement Danes, both churches in London. The traditional recipe calls for equal parts orange juice and lemon juice served over ice in a highball glass. There are many variations, in which the lemon juice is replaced with a sweeter drink (like lemonade), or even a carbonated citrus-flavored soft drink (like Sprite, 7-Up, or Fanta Lemon).
