Puffed Pork Scratchings

Crispy, puffed pork scratchings made from skin-on fat are a world away from the dusty packets behind the bar. Done properly, they’re rich, golden, and blistered with savoury depth and just enough chew. This recipe uses skin with a good 1cm layer of fat attached — the key to perfect puff.

INGREDIENTS
  • Pork skin with 1cm fat attached (as much as you like)
  • Coarse sea salt
  • Optional seasonings: white pepper, smoked paprika, cider vinegar powder, chilli flakes
METHOD

  1. Prep the skin:
    • Slice the pork skin into strips or chunks about 2–3cm wide.
    • Pat dry thoroughly and sprinkle all over with sea salt.
    • Place skin-side up in a roasting tin and leave uncovered in the fridge overnight to air-dry.
  2. Slow render:
    • Preheat the oven to 140°C fan.
    • Roast the skin skin-side up in a shallow tray for 90 minutes, turning halfway through.
    • This step slowly renders the fat while beginning to dry the surface.
  3. Cool and dry:
    • Remove from the oven and place the pieces on a wire rack to cool completely. This helps the surface firm up, which improves the final puff.
  4. Final roast for crisping:
    • Turn the oven up to 220°C fan.
    • Return the cooled skin to a clean dry tray, skin-side up again, and roast for 15–25 minutes, until golden, puffed and blistered.
    • Keep an eye on them — they can go from golden to burnt quickly.
  5. Season:
    • Toss with extra sea salt or any dry seasoning you like while still warm.

Multi-Cooker Option

Ninja Foodi / Air Fryer:

  • After slow-roasting and cooling, crisp the scratchings in the Air Crisp mode at 200°C for 5–10 minutes until blistered and golden.
  • Work in batches to avoid overcrowding.
  • Line the basket to catch rendered fat for later use.
  • Let cool slightly before seasoning.

Hot Tips

  • The fat is essential — too lean and they won’t puff.
  • Drying overnight in the fridge helps ensure a crispy result.
  • Save the rendered fat from step 2 for roasting potatoes.
  • Store cooled scratchings in an airtight tub for up to a week.
  • You can freeze the cooked, cooled scratchings and reheat in a hot oven to crisp them back up.
