- STEP 1
Put the onions, carrots, peppers, spring onions, cumin and garlic into a large pan and place the beef fillet on top. Pour over 4 tsp oil and the worcester sauce. Leave to marinade at least 12 hours or overnight in the fridge.
- STEP 2
Take out the beef, reserving the marinade liquid and vegetables and place into a deep frying pan or saucepan with 6 tsp of oil. Seal the beef on all sides until it is a dark brown (almost black) in colour. Add the marinade liquid, the vegetables, the white wine to the pan and add salt and pepper to taste.
Cook uncovered on a low heat for about 4 hours.
- STEP 3
Remove the beef and cut into slices approx 1 cm wide.
Strain the gravy and serve over the beef.
