From the Guardian, directions for making a shooter's sandwich -- a sandwich made by hollowing out a round loaf, filling it with two steaks and some cooked mushrooms, wrapping and tying it, and then compressing and slicing it. Yum!
Don't bother resting the steaks. Work fast and tuck the first one, dripping and hot, straight into the bottom of the hollow loaf...Dollop in your hot mushroom mixture...Tuck your second steak over the mushrooms. At this stage I usually smear hot horseradish on the top steak and Dijon mustard on the inside of the lid...How to make a shooter's sandwich (via Reddit)
Wrap in greaseproof paper and tie with butcher's string like this. Then wrap in two layers of foil and smush flat under a heavy cutting board and as many weights as you can find
Leave under the weights in a reasonably cool place (don't refrigerate) for at least six hours or preferably overnight. Remove the foil and cut through string, paper and sandwich
