To make the Chinese Five Spice powder, toast the ingredients in a dry pan, swirling them gently around until they become fragrant then let cool

Add to a spice grinder or bash with a pestle and morter until powdered

Store in a small jar out of the sunlight. I like to use the empty cinnamon stick jar

Rub each side of the pork with the oil, sprinkle the 5 spice over both sides, rub in, cover and set aside in the fridge to marinate for at least 30 minutes

For the sauce, mix all the ingredients together in a saucepan and let simmer for 5 minutes. Taste and add more vinegar as required

Fry or grill the pork steaks for a couple of minutes on each side until cooked through
