Caviar is classified as an aperatif, which itself is a culinary item that prepares the palette for a substantial meal. An aperatif can be either a beverage or a comestible, and is often enjoyed during a little period we like to call 'cocktail hour'.
"Cocktail is a stimulating liquor composed of spirits of any kind, sugar, water, and bitters — it is vulgarly called a bittered sling and is supposed to be an excellent electioneering potion, inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head. It is said, also to be of great use to a Democratic candidate: because a person, having swallowed a glass of it, is ready to swallow anything else."
Dressing for Cocktails
For men, in the 1930s, acceptable cocktail attire was less formal than evening wear and usually consisted of a suit or trousers, jacket and tie or bow tie. In the 1950s men often sported rayon trousers, with custom-made jackets. Cotton or silk shirts were accessorised with slender ties and ascots. However,by the 1960s, ties were discarded along with interest in retaining the elegant ritual, unwittingly replaced by an interest in recreational drugs and the 'Revolution'.
