I used bacon and pancetta as well as mince, thickened and reduced the tomato sauce before putting it in with everything else. I also threw a cinnamon stick, bay leaves, brown sugar, half a jar of jalepenos and a shit load of hot chili powder in to season it and stewed it on the hob for one and a half hours.
Sounds good. If I can be arsed I tend to use both pork and beef mince, often with stewing steak chunks as well. Loads of cumin, chilli powder, chipotle (dried smoked jalapenos) if I have it, stock and the obligatory tomatoes and bay leaves. Hob or oven at low heat for as long as I can bear.
Tomorrow and it's a pork and beef mince mix, taken out of the freezer.
