Steak Medici

There's nothing like a great steak with a glossy sauce to look forward to on a Saturday night.  I've cooked this for friends many times and it always goes down well long as everyone likes their steak medium rare, as I can't cook it any other way.  Creamy buttered mash and peas make wonderful bedfellows, or keep it really simple with crusty bread and a tomato salad.  Let's hope it looks as good as this photo.

Ingredients
50g butter
4 sirloin steaks cut about 2-3cm thick
225g mushrooms, sliced
A sprinkle of salt and freshly ground black pepper
60ml of port
Chopped parsley, as garnish.

Method
Melt half the butter in a large frying pan.  If you add a teasp oil it stops the butter from burning.  When it is very hot add the steaks, two at a time and brown them on both sides.  Continue to fry according to taste, ideally 3 minutes on each side for medium rare, 5 minutes for medium.  Remove them from the pan and keep warm.  Reduce the heat and add the remaining butter to the pan.  Stir in the sliced mushrooms and season.  Cook, stirring until the mushrooms are tender but still firm.
Add the port, stirring to loosen any sediment on the bottom of the pan.  Spoon the mushroom and port mixture over the steaks and garnish with the parsley and serve immediately.
