Add tomato paste and tomatoes, cook for another 10 minutes.
Add meat and stock. Dial the heat up until it's boiling, then lower and simmer for 10 minutes if you're using minced beef, at least 20 if you're using a chopped tender cut, or 1 to 2 hours if you're using a cheaper cut.
Season with salt and pepper.

Turn off heat, add milky stuff (coconut milk or cream), and stir.
