1Preheat the oven to 220°C, fan 200°C, gas 7. Put the beef dripping or oil in a roasting tin and heat in the oven for 10 minutes. Season the beef. Put the onions and carrots in the tin and put the beef on top. Roast for 30 minutes, then baste and add the wine. Roast for a further 30 minutes, then add 250ml boiling water. Roast for a further 10 minutes for rare beef.
2To make the salsa verde, blend all of the ingredients in a liquidiser to a coarse purée and season.
3Rest the beef, covered with foil, on a board for 20-30 minutes. Put the tin on the hob and simmer for a few minutes. Skim off the fat and take out the vegetables (you don’t need them for this recipe, but you can eat them). Serve thick slices of beef with the tin juices and salsa verde.
