What is a hot posset? I know it is a drink from the medieval times, but that is all.
Posset is a Middle English word of uncertain origin, but there’s no uncertainty about what it is. It’s a drink composed of hot milk curdled with ale, wine, or other liquor, with sugar and spices sometimes added. It was (and still is) popular not only as a delicacy but also as a remedy for colds and other infections.
