Heat the butter and oil in the potjie.
Brown the meat and set aside.
Add the prepared onion, garlic, carrot, celery and rosemary and fry until softened.
Add the remaining veggies and heat through.
Add the meat, followed by the hot stock, tomato paste and wine.
Cover and simmer gently over moderate heat for 4 hours.
Add more wine if the liquid evaporates too rapidly.
