In a bowl, combine pork, brown sugar, salt, garlic, and pepper. Massage thoroughly until the seasonings are well dissolved and incorporated.
Add red food coloring and continue to mix until evenly colored. Add pineapple juice and mix.
Store in a covered container or ziplock bag and refrigerate overnight to cure.
In a pan over medium heat, add pork including marinade and enough water to cover. Bring to a boil.
Lower heat, cover and simmer until meat is tender and cooked through, adding more water in 1/2 cup increments as needed.
When water is completely absorbed and meat is tender, add oil and cook, stirring regularly, until meat caramelizes. Serve hot.
