Cocktails with brandy or cognac : Brandy Alexander

Brandy Alexander is a sweet, brandy-based cocktail that became popular during the early 20th century.
It was supposedly created at the time of the wedding of Mary, Princess Royal and Countess of Harewood and Viscount Lascelles, in London, in 1922 (Source: Classic Cocktail Club, Milan, Italy)
The Brandy Alexander is based on an earlier, gin-based cocktail called simply an "Alexander".
It is sometimes confused with a drink called a "Panama," which is made with light crème de cacao, instead of the dark crème de cacao used for the Brandy Alexander.
