1. Place the butter and oil in a frying pan, turn to low to let it melt.
2. Slice the potatoes into 1/8" round slices, and add to the pan. Mix the potatoes up with the melted butter and oil.
3. Sprinkle the spices onto the potatoes, 1/4 Teaspoon of salt, 2 teaspoons of the black pepper, and 1 teaspoon of the blacken. Mix this up, then add the rest, and mix it up again.
4. Cover the pan, and cook for a total of about 15 - 20 minutes, stirring every 5 - 7 minutes. If you find them burning, without getting soft, turn the heat down a bit. If they're getting soft, with no browning, turn the heat up a little. The potatoes are done, when they're soft.
5. Add ham pieces after the last stirring, and cover again. The ham will steam to re-heat. Cook another 5 minutes, and serve.
