Rinse the trotters under clean running water
Add water into a deep pot, add the trotters (ensure that the trotters are completely covered with water, add more water if necessary)
1 medium pork trotters
Add the stock cube into the pot, close the pot, and allow to boil on medium heat until soft; this should take about three hours
1 beef stock cube
Once the trotters are soft, drain excess water if there is any (pour the water into a bowl to use at a later stage)
In a separate pot, add a little bit of cooking oil, followed by the onion. Fry until translucent, and then add the trotters and give them a little toss
1 medium onion (chopped)
Pour in the spice and allow the spice to fry for about five minutes. Follow with the tomato paste and the water you drained earlier or fresh water
3 tablespoon barbeque spice, 3 tablespoon tomato paste
Allow to simmer for 5 minutes before serving with hot pap.
