The size of the pork rinds and the heat are the two main factors that affect the cooking time. Generally speaking, the larger the skin, the longer it will take. If cooked over moderate heat, the time needed is usually around two hours, which ensures that the pork rinds are fully cooked. If cooked over medium heat, the time can be reduced to about 30 minutes so that the pork rinds are not only cooked, but not too soft. If cooked over high heat, the pork rinds can be pierced with chopsticks in about 10 minutes, but they may not be fully cooked at that point, so it is recommended to cook them for a few more minutes. In addition, pork rinds need to be blanched before cooking to remove the fishy flavor and impurities, and the blanching time is usually about 5 minutes.
