Sufficient for 3 to 4 serves you will need

500/600gms of Pork mince or diced pork
250g Sweet Potato, peeled and small dice
1 large red onion (100gms) peeled and sliced.
5 fresh plums, washed, de-stoned and halved (about 400gms)
2 cloves of garlic, crushed
1 long green chilli, fine diced (optional)

For the Sauce Mix together

1 tablespoon of Soy Sauce
2 tablespoons of sugar
2 tablespoons of white wine vinegar
¼ teaspoon of Chinese five spice.

This can be made in a wok or a large frypan.
Heat you pan on a high heat until smoking and then add the pork and continue to cook on high, stirring frequently for around 5 minutes until it is well browned and any fat/water has cook out. Use a slotted spoon to remove the meat and set aside.

Return the pan to a moderate heat, adding a splash of oil if necessary and then the potato, onion, chilli if suing and the garlic. Stir fry for 5 minutes before adding the plums, stir well and continue cooking for 3 minutes before adding in the sauce mixture and let it gently bubble away for a few more minutes.

Add the pork to the pan and allow it to simmer gently until the pork is cooked through. The sauce should thicken, but if there is too much liquid this can be thickened with an arrowroot/cornflour and water mix.

Once the sauce is of your desired consistency and colour, hopefully deep red from the plums it should be ready. Test for the right balance of sweet and sour and adjust if necessary and serve!
