Heat the oil in a large, deep sauté pan, add the onion and fry for a few mins until starting to soften.
Stir in the ginger and cook, stirring frequently, for about 8-10 mins until the onion is golden.
Stir in the spice group, and fry until toasted.
Stir in the apple group, then cover the pan and cook for 10 mins.
Stir in the mango group, then cover and cook for 20 mins more until the apple is pulpy and the mango is tender.
Pour in the vinegar group, then leave to simmer uncovered for 30 mins, stirring frequently (especially towards the end of the cooking time so that it doesn’t stick) until the mixture is pulpy rather than watery.
DONE!
