This is classic Stroganoff ....never fails ..retro recipe !
1 lb (450g) Fillet of Beef
1 1/2 Medium Onions
4 oz (100g) Closed Cap Mushrooms
1 oz (25g) Butter
1/8 Pint (75ml) Soured Cream
Salt & Pepper
Slice the Beef into 2in (5cm) strips - the thickness of your finger. Slice the Onions thinly. Cut the stems off the Mushrooms and also slice thinly.
Over a low heat melt half the butter (with a dash of Olive Oil) in a frying pan and add the onions. Move around regularly until they are soft and see through .. Add the sliced mushrooms and toss around for a minute or so until they are soft and coated with the juices.
Spoon out the Onions and Mushrooms into a dish.
Add the remaining butter to the frying pan and allow it to get very hot - so that it froths. Drop in the beef strips and fry briskly on all sides. The beef really needs only to be browned and not over-cooked in the middle. A couple of minutes at the most.
Tip the onions and mushrooms back into the pan. Season well with salt & pepper. Add the soured cream and cook at the same heat for another minute or so that the cream reduces a bit .
I make Stroganoff the same way as shaneystar2 except that I add a 'dollop' of Sainsburys French Dark mustard. It just adds that wee extra zing. According to Rick Stein, Beeef Stroganoff should be served with matchstick potatoes!
