Beef chilli with dark chocolate

Method

1. Heat the oil in a medium pan over a low heat. Add the onion and cook for 5 minutes, stirring occasionally, until translucent. Add the garlic, pepper and vine tomatoes and cook, stirring, for 6-8 minutes until the tomatoes have softened.
2. Make a space in the centre of the mixture, then add the chilli powder, paprika and cumin. Mix well, then cook for around 5 minutes.
3. Meanwhile, season and cook the mince in a separate pan over a high heat for 8 minutes or until browned.
4. Drain the mince, then add it to the tomato mixture, along with the wine. Stir over a high heat until the wine evaporates. Stir in the oregano and thyme, then the tomato paste. Reduce the heat to low and cook for 1 minute. Add the tinned tomatoes and stock. Cook for 5 minutes; stir occasionally.
5. Add the bay and cinnamon, then cover the pan with a lid and simmer for 30 minutes, stirring now and then.
6. Remove the lid and stir in the beans and sweetcorn, then cook, uncovered, for 10 minutes. Taste and season, then stir in the chocolate until it has melted. Remove the pan from the heat, then discard the bay leaves and cinnamon stick. Serve in bowls topped with avocado slices, soured cream, coriander sprigs and a grind of black pepper, with soft flour tortillas on the side, if you like.
