This unusual form with an even odder name begs the question: what is a posset pot?
Posset pots were specially designed for the consumption of a warm, spiced drink popular from the Medieval period into the 19th century. The nourishing beverage, posset, was used to strengthen new mothers, the sick, or the elderly. Though it turns my stomach slightly to think of it, a good posset recipe should result in several layers caused by curdling. The drink is made from milk beaten with eggs, sugar, and spices and curdled with ale or wine, but bread could be added to thicken it. The curdled milk rises to the top, the eggs create a custard mid-layer, and at the bottom is a warm spicy alcoholic drink, accessible only through the straw-like spout of a posset pot’s distinctive shape.
