Roast pork belly sub with crackling, balsamic onions and apple sauce

1.Rub pork skin with salt and refrigerate uncovered overnight to dry out.

2.Preheat oven to 120C and line a roasting pan with baking paper. For spiced onion marinade, process ingredients and 60ml water in a blender until smooth, transfer to a small saucepan over high heat, bring to the boil, then pour into roasting pan.

3.Place pork in pan on top of marinade and roast until fork-tender (5-5½ hours).

4.Meanwhile, for apple sauce, combine ingredients in a saucepan with a large pinch of salt. Bring to a simmer over medium-high heat and stir occasionally until apple is translucent (5-7 minutes). Transfer to a blender and process until smooth, adding extra lemon juice to taste. Set aside at room temperature until required.

5.Combine onion and balsamic vinegar in a bowl. Remove pork from pan (discard baking paper and marinade), increase oven to 250C and clean pan. Return pork to pan, scatter onion mixture in, season to taste and roast until skin has crackled (15-20 minutes). Set pork aside uncovered to rest (15 minutes) and remove crackling. Return pan with onion to oven and roast until tender, but still has some bite (10-15 minutes). If any skin hasn’t crackled, add to pan to finish crackling.

6.Partly split baguettes lengthways and press open. Chop pork and crackling into rough 4cm pieces and stuff pork into baguettes. Top with balsamic onions, apple sauce, crackling and mayonnaise, sprinkle with parsley and serve.
