Put a large saucepan on the stove and heat it up, wait until it gets hot in the saucepan. Then cover the bottom of the pot with olive oil and fry the minced meat. In the meantime, dice the onion and garlic and add to the meat, fry briefly, then deglaze with the red wine. Crush the spices (cumin, salt, pepper) in a mortar and add to the meat, reduce the red wine. Turn the stove down to half the flame.
Put on rubber gloves and chop all the chillies (with or without seeds, depending on your taste) and add to the meat. Drain the beans and corn and add to the meat, as well as the tomatoes. Add tomato paste to taste and simmer for a good 45 minutes.
Then break the chocolate into pieces, distribute in the chilli and let simmer again for a good 45 minutes. Season to taste again with salt and pepper.
Serve in deep plates. Personally, I don`t serve side dishes, either red wine or a cold beer as a drink. For people for whom this is too spicy, I recommend serving sour cream separately, which can then be stirred in as desired to soften it. And like any stew, it tastes even better the next day.
