Ingredients:
4 beef fillets (about 200g each)
225g sour cream
110g onions, finely chopped
50g butter
1 tsp mixed peppercorns, finely ground
2 tbsp white wine
2 tsp brandy
Method:
Heat a little olive oil in a pan over high heat and use to seal the beef on both sides until nicely browned. Remove from the pan and set aside.
Lower the heat and use the pan to fry the onions gently (using the remaining oil) until just soft (about 6 minutes) then add the brandy, the white wine and the pepper. Reduce the heat to a gently simmer and cook until all the liquid has almost gone.
When the pan is almost dry add the sour cream and the butter and bring the mixture to a boil. Return the meat to the pan and continue cooking to your desired level of done-ness (about 4 minutes for rare and up to 12 minutes for well done).
Serve with roast potatoes and julienned seasonal vegetables.
