Although similar to a syllabub, the posset is much richer because it is more like a custard than a cream. Possets were served in a ceramic posset pot, which looked a little like a teapot with two handles. They were usually very decorative and were extremely expensive to buy. This dish is therefore, again, one of high standard.
Possets were originally more drinks than they were puddings and were often given to people in rich households when they were feeling unwell.
