Squeeze the wine-soaked bread firmly to remove excess liquid. In a large bowl combine the minced meat, squeezed bread, ground pepper, fish sauce, crushed myrtle or juniper berries and a generous pinch of salt. Mix thoroughly with your hands until completely combined. The bread crumb binder will give the mixture a slightly softer, more yielding texture than a standard burger patty.
Divide into 4 equal portions. Form each into a patty approximately 2cm thick. Press a small amount of pine nuts and a few whole peppercorns into the centre of each patty, then fold the meat over them and reshape. The pine nuts and peppercorns inside the patty are specifically documented in the Apicius text and produce a textural surprise as you eat.
Wrap each patty in caul fat if using, or lay a thin strip of streaky bacon across the top and bottom. If using neither, the patties will cook perfectly well unwrapped.
