Heat the oil in a large, heavy-based saucepan with a lid and fry the onion and garlic until softened. Increase the heat and add the mince, cooking quickly until browned and breaking down any chunks of meat with a wooden spoon. Pour in the red wine, if using, and boil for 2–3 minutes.
Stir in the tomatoes, tomato purée, fresh chilli or chilli flakes, cumin, ground coriander, cinnamon and Worcestershire sauce and crumble in the stock cube. Season well with salt and pepper.
Bring to a simmer, cover with a lid and cook over a gentle heat for about 50 minutes to 1 hour, stirring occasionally until the mixture is rich and thickened.
during this time, add chopped banana, finely chopped apple and the cocao (personally I add these around 25 minutes after starting the simmer).
Add the kidney beans and fresh coriander. Cook for a further 10 minutes, uncovered, before removing from the heat and add any extra seasoning if necessary.
We prefer serving on a bed of Corriander Rice with Lime Wedges and Sour Cream
