Enter my knowledgeable butcher. I had heard that hanger (or onglet) steak was a cheap alternative that is normally used for slow cooking. Unfortunately there was no hanger available as it was all frozen, but not to worry, as I was assured that a few slices of topside would be a good substitute. My butcher took off a few thick steaks from the topside and butterflied them for me, I couldn’t wait to give it a try. The topside came in at £12.95 per kg whereas sirloin would have been £24.50 per kg.
