I actually cooked this a little while ago when rump steak was on a 'third off' special offer at Tesco and decided to fry the steak in butter rather than fat or oil. I have a particular fondness for salty butter and I like the delicate rounded taste it can give to the meat, fish or vegetable it is cooked in. Of course a shake or two of black pepper near the end of the cooking process gives it another level of flavour. My mouth was watering even before it went into the pan!
I had prepared and mostly cooked some new potatoes, carrots and green beans before I gently fried the steak (twelve minutes) with a few button mushrooms. A succulent and perfect simple evening meal. It melted in the mouth!
