"This is rich and full of pork goodness," says Boetz, "and the parsley sauce cuts the richness of the meat." Begin this recipe a day ahead to press the pork hock.

Preheat oven to 180C. For braising liquor, heat oil in a large saucepan over medium-high heat, add onion and garlic and stir occasionally until caramelised (8-10 minutes). Add herbs, deglaze pan with wine, bring to the boil, add stock, bring back to the boil, season to taste and set aside.
Heat half the oil in a large casserole over medium heat, add hock and cook, turning occasionally, until browned (2-3 minutes). Pour braising liquor over, bring to the boil, skim off excess fat, cover tightly with foil, then a lid, and braise in oven until meat is falling from the bone (2 hours). Remove hock from braising liquor (discard liquid), remove bone from hock with tongs (discard bone) and press meat into a 10cm square cake tin lined with baking paper. Cover closely with baking paper, then place a slightly smaller cake tin or foil-wrapped piece of stiff cardboard on top and weight with food cans. Refrigerate overnight to press.
For parsley and young garlic sauce, cook egg in a saucepan of boiling water until hard-boiled (8 minutes). Drain, refresh under cold running water, then peel and set aside. Stir herbs, garlic, dill pickle and lemon rind in a bowl to combine, add oil, vinegar and sugar, season to taste and stir to combine well. Finely grate in egg, gently fold to combine and set aside.
Unmould hock meat from tin and slice into 2cm-thick strips (about 5cm long). Heat remaining oil in a non-stick frying pan, add meat slices and cook, turning once, until crisp (4-5 minutes). Drain on absorbent paper, top with a little parsley and young garlic sauce and lemon rind and serve hot with lemon wedges.
