Tips for the best pork crackling

There's nothing like an awesome pork roast with crunchy crackling to go with it! Here are some tips to get the crackling just right:
1. score the skin
2. rub plenty of salt into the skin (some people also add lemon juice or canola oil, but using just salt works fine)
3. Leave uncovered in the fridge overnight
4. Take it out of the fridge 3 hours before cooking to ensure it is at room temperature before placing it in the oven
5. Turn the oven on as hot as it goes before putting the pork in
6. Cook on high for 30 minutes
7. Turn the oven down to 170 degrees celsius for the remainder of the cooking time (remember 30 minutes for every 500 grams)
