Spicy chipotle beef

METHOD

1. Heat a heavy-based casserole dish over high heat. Add beef and sauté until brown and cooked through. Breaking up meat with a fork, cook for 8–10 minutes. Transfer to a large bowl. Add onions and garlic to the same pot. Sauté until onions are tender, approximately 5–8 minutes. Add chilli powder. Sauté until fragrant, 1–2 minutes. Add beef, stock, beer, worcestershire sauce, tomatoes and chilli peppers. Cover partially; simmer until thick, stirring often, about 1 hour.
2. Gradually stir in polenta, then black beans. Simmer until heated through. Season generously with salt and pepper.
3. Whisk crème fraîche with lime juice and zest. Season with salt.
4. Spoon chilli into bowls and serve with lime crème fraîche and tortilla chips.
