Wash the meat and dab dry. Cut the rind crosswise with a sharp knife close together in strips. Rub the rind with 1-2 teaspoons of salt, season the meat side with salt and pepper. Place on a baking tray with the rind facing upwards.
Roast in the preheated oven (electric cooker: 150 °C/circulating air: 125 °C/gas: see manufacturer) for approx. 1 3⁄4 hours. Switch on the oven grill. Continue roasting for approx. 10 minutes until the crust puffs up (take care not to burn). Arrange roast.
