What is "chocolataire"

A chocolataire is a type of social gathering which ranges from large events (such as fund raising and invitation only) to smaller functions (similar in structure to informal tea parties), in which all food and drink are composed of or contain some form of chocolate. Considered obsolete by some, this entertainment was at its peak popularity around the turn of the 20th century (the process for making milk chocolate having been brought to market in 1875), and was seen as a novel alternative to the other forms of social gathering at the time.
