Start hot: 220–240°C lid temp
Cook for 30–60 minutes, I have the lid open a crack so I can visually inspect the roast without taking the lid off
Once you asre happy with the crackling, drop the temperature to around 160, cook until you hit 63℃ (1 to 2 hours)
Once cooked remove from the BBQ and rest (I put it uncovered into an oven at 60 ℃
Use the stock to make your gravy
