Dry the meat off with paper towels, ensuring there is no residual moisture. Place the sesame seeds and salt in a mortar and pestle and lightly pound them. You don't need anything like a paste, just enough to crack open some of the seeds to release the flavour and aroma. Add the white pepper and mix with a spoon. Place this mixture on a board and then press the pork loin steaks into the lightly smashed sesame seeds. Make sure you coat both sides well and then proceed with the rest of the meat in the same way. You can do this ahead of time and leave the steaks in the fridge, covered, until you are ready to use them.
Preheat oven to 200 C. Heat a few tablespoons of oil in a medium sized frying pan. Wait until the oil is very hot (almost smoking) and then add the steaks. Brown them evenly on both sides until the steaks are lightly golden. Put them on a baking sheet . 15 minutes before sitting down to eat, place your steaks in the hot oven. Bake for a further 5- 10 minutes. The cooking time will depend on the thickness of the steaks. Leave the steaks to rest out of the oven at least 5 minutes, before slicing. To serve, slice the steaks thinly.
Place the drained tinned cherries and the juice in a blender. Whizz until smooth. Transfer this to a small saucepan and bring the mixture to a slow simmer. Add all the other ingredients and stir occasionally. Continue to simmer the sauce until it reduces by about 1/2 the original amount. The sauce should be thick and syrupy. Taste and adjust accordingly. The sauce should be sweet and tangy. You can make the sauce up to 3 days ahead. Serve the sauce either slightly warm or at room temperature.
Serve this with stir fried vegetables or steamed cabbage and a bowl of white sticky rice.
