Place the dried ancho and dried red peppers in a bowl of hot water to soak for at least 30 minutes.
Drain.
Add ¼ cup (60 mL) of oil into large pot and get it good and hot. Take cubed meat and brown in pot on all sides.
Remove browned cubes from pot and set aside.
Combine remaining olive oil, cumin seeds, garlic powder, cayenne pepper, reconstituted peppers and chipotle peppers in food processor and process for 30 seconds to 1 minute.
Add in both cans of tomatoes (crushed and whole), tomato paste, chopped peppers and the browned cubed meat.
Stir to mix all ingredients and simmer for 1½–2 hours. The longer you cook the more flavor you get.
