Posset

A posset (/ˈpɒsət/, also historically spelled poshote, poshotte, poosay) was originally a popular British hot drink made of milk curdled with wine or ale, often spiced,^[1] which was often used as a remedy.

The original drink became extinct and the name was revived in the 19th century and applied to a cream, sugar and citrus-based confection, which is consumed today as a cold set dessert nearly indistinguishable from syllabub.
