If you have ever been to the town of Zastron in the Eastern Free-State, South-Africa, you will know how intensely icy the weather can be during winter. On a recent visit to the in-laws, I stumbled upon punnets of wonderfully ripe plums in the local community market. I thought about creating something that will warm you up from the inside, and what better than to combine plums with the truly South-African sherry derivative of Old Brown’s Sherry – popularly known as OBS. This jam will make your toes curl warmly. Guaranteed.
