Praga ham is a typical speciality of the central European charcuterie industry, which Trieste has inherited through centuries of belonging to the Austro-Hungarian empire. The unique aroma of Principe's Praga ham is the result of processing methods that differ from those of traditional cooked hams.

The cooking stage does not use wet steam but instead is carried out in special hot-air ovens. The subsequent smoking stage is completely natural and based exclusively on beech wood.
