Author and chef ronaldo linares says, 'This recipe takes the classic pork shoulder dish (pernil) and makes it healthier while still giving you the amazing cubano flavor that we love. I have substituted pork tenderloin for pork shoulder in this version of the recipe. I can hear my fathers voice screaming at me, 'oye, chico, what are you doing changing the dish?' im not changing the essence of the dish, im just modifying it so people can enjoy it in a healthier way.
