Using a knife, scrape the pork skin to remove any remaining hairs.
Rub the skin with coarse salt and wash well.
Slice the pork skin into 1.5” (4cm) long strips.
In a pot, bring water to a strong boil. Add a bruised stalk of lemongrass as a deodorizer and cook the pork skin until it becomes transparent and softens. Be careful not to overcook the skin or it will become gooey and sticky.
Remove the skin from the water; using a knife, discard all the remaining subcutaneous fat.
Slice the pork skin very thinly along the width of the strips.
Let the skin strips soak in a 1:1 solution of lime juice and water for 5-10 minutes, which will help to eliminate the stickiness of the pork skin.
